I draw pretty good Sci-Fi / Fantasy related stuff, but only concepts that come from my mind. When I try to draw my favourite characters (Sephiroth <3) or something special, I always fail
When I draw I usually do a sort of "Picasso way of Drawing": when he was painting, he was starting with something, then draw something over it, using the previous one as base, and so on.
For me, it's something like it, for example, today I just started by drawing a sword, then used it as a base for a space ship, then transformed the spaceship into a canon, and then I used the whole as a leg for an insect-themed robot...
I have time, I do this in class along with Pen Spinning
Too bad, I don't have a scanner
