After finding conceptart.org a few weeks ago, I became addicted, so I'd like to contribute. First I'll post a small chronological sampling from my two sketchbooks.
I'm 25 now, and while I used to draw as a kid, I haven't drawn much at all in the past ten years. Here's some preliminary sketches I've spat out over the past month (I've been drawing voraciously since the beginning of April). While I have the imagination, I lack the technical skill, so many of the artists on these forums are great inspirations for me. Oh, what I could have been if I had kept drawing since my childhood.
Anyways, here's some stuff from my sketchbook (and since these are my better pictures, just imagine what the rest of it looks like! egh!).
I'll just post a few images to keep your eyes from falling out.
And these sketches are my tribute to conceptart.org. I spend quite a bit of time emulating other artists.
Oops, out of time. I'll post the rest of the sample tomorrow.
