Light and Darkness

At last! I drew something!
It's pretty generic in what it's a picture OF (probably), but I couldn't really think of anything else to draw, so I... experimented with some things.
It bothers me that basically everyone I see on dA who draws dragons and other similar things aspires to draw them in the same old way... With neat lines, perfect anatomy, interesting but believable poses... But why? Why do people care so much about neatness and accuracy or feasibility of anatomy in their pictures?
It also bothers me when I get comments like "this looks nice but it'd be better if it were refined a bit ^_^" or comments regarding my rather poor anatomy-drawing skills... I don't usually TRY to draw 'realistic' anatomy, and the mere THOUGHT of 'refining' my images makes me go "ugh".
Anyway, this is all completely irrelevant! LOOK! A PICTURE!! o_O

This took 50 minutes in Photoshop (Really. People have doubted I make these things as quick as I claim before, but as you might be able to tell from the result, my style does involve being rather quick and sloppy and so on, and I usually get bored after an hour or so and call it done...)
