When you start learning to draw, soon you realize: the big part of this artistry is just craftsmanship and technique. When you are proficient in the primary techniques, your creativeness can rely on these basics. This leaves you more freedom for developing your drawing skills and imagination rather than focusing on applying the basic techniques decently.
Therefore it's a great thought to practice these primary drawing techniques on a regular basis. Especially when you are starting to learn to draw, much exercising these primary techniques will quicken your drawing success.

Learn to Draw Hatchings and Cross-Hatchings

Hatching means to draw a lot parallel lines approximately. Other than in conventional shadings the lines are not allowed to touch one another! Though there's still a small blank space between the lines they build an area apparently shaded strongly.

Cross-hatching  takes it one step  farther.  When you're  exercising cross-hatching you  overlay one  set of hatchings with an additional  set  orthogonal to the first one.  Thus cross hatchings get  a lot  denser and  solider than (single) hatchings.
Drawing hatchings  calls for  precision. So  practicing hatchings is  also a  outstanding  chance to  exercise your  drawing  precision.  When starting  begin to  fill  blank  sheets of paper with hatchings and cross-hatchings  without a  special  subject in  your eye.
 Once you've  acquired  a certain level of   technique, you  ought to  try first  simple  studies.  Choose such  sceneries that  consist of  enough shadow.  Try to  depict this  scene  not  using outlines.  Instead  rely  entirely on   translating the  shadows and dark areas into hatchings. Let the hatchings'  direction  play along the  subjects you're  depicting. For drawing  darker areas and  shadows  lay the lines of your hatching  nearer  together or use cross hatching.

You should be learning to Draw Shadings

To draw shadings is more usual than hatching.  It is  more instinctual and  needs  lower  experience. When drawing shadings you  just  fill  areas of your drawing with your pencil. By  varying the softness of your pencil, the  pressure you  employ and the  count of  layers of shadings you  produce you  control the  shades you  create.
 Like when creating hatchings  you  draw shadings by drawing lots of lines. For now you draw them so close to  one another they  overlap and  merge  entirely. Shadings  made out of lines still  bear a  direction (though not as strong as in hatchings). So  be aware to  align your shadings'  direction with the  forms of the  objects  you are  depicting. To  get the shading  heavier you  have to  employ the same  methods as when  doing cross hatching.
 Another way for drawing shadings  requires to draw   countless  very  little  circles  densely together so they  merge and blend.  Blendings  made this way are  extremely  even and  miss a hidden  direction. The advantage: you  don't  have to  keep an eye on  the shading's hidden  direction.
 Ideally you  start  practicing shadings right now.  Choose  a few  sheets of paper,  outline  a few  bare  forms like  rectangles and  start to  fill them  with shadings.  Try to  get them as  smooth as  possible and  apply all the  different  techniques  explained before.
 Again  once  you have  reached  decent  experience,  try to  begin using the  methods  acquired on real-world  sceneries.

Use  Different  angles and types of perspective

 Besides  doing shadings and hatchings the  most important  skill you  have to  know  when  beginning to learn drawing, is a  sound  apprehension of perspective.
There are  a few  rules that  may  assist you in  constructing perspectively  correct  drawings. But first it's  essential you  practice your eye to  recognize  common  forms and structures.
 Choose  simple  sceneries mostly  containing of  straight lines and not too much  curves.  Then  draw  those  scenes by drawing  only the  outline. This way  you are able to  focus on  interpreting  dimensions and perspective. But  don't  stop here,  reiterate this  practice by drawing  the same  scenery  again and again from  different  angles.
 You'll  see with  every  repeating  you'll  understand the  scene  better and your  skills to  capture and  picture the  dimensions of any subject will  increase  greatly.

 What  Next?

These three  practices are the  most crucial  while  studying to draw. There are  more  common  methods and  techniques you  might want to learn.  You could  learn your drawing skills  by yourself -  simply go out and draw  life  sceneries.  Start with  simple ones and  step-up the  degree of  difficultness  while you  advance.  Also you  could learn drawing  employing  exercises  designed and  proved to  ensure  best  advancements for your drawing  skills.
