So let's get on with the fun! Something about blogs that has always bothered (and that I have admittedly fallen into) is this sort of egocentrism of posting stuff for the entirely wrong reasons. Mainly, to get compliments and praise.
Praise is a natural desire, but I don't feel it should be the focal point of any artist. Now switch gears real quick with me... how many of you are afraid of your sketchbook like me? I often put such unnecessary pressure on myself to make every page "perfect". Well, the more I do this stuff the more I realize that art is not about perfection, but about honesty. Honesty can seem like such a vague word, but in short it's about communicating your raw unadulterated feeling on whatever you are seeing, reading, absorbing from life around you and reinterpreting it in the way you feel/see it. Could I draw these better if I put another sheet on top and reworked them? Will there be folks who sees these and aren't impressed? Of course, but that's not the point! The point is motive, and the motive is honesty and sincerity.
I certainly won't argue that basic drawing isn't important to the communication of your feelings, but sometimes we get too concerned with the mastery of the visual presentation. Sometimes there is a raw feeling communicated in the most crude of drawings that I hardly if ever see in extremely refined drawings. So don't be afraid to make mistakes and show'em to people. Remember, they ain't perfect either... what matters is you communicating your feelings, even if that left arm is a little too long.
