Capensis are you using a mouse to do digital art in photoshop or did you buy a Wacom Intuos pen & tablet? I have a tablet but am not doing all the digital art I intended to when I bought it. It's hard to learn the habit, like relearning how to draw all over again. I already know how to use a pencil so I find myself reverting to analog!
Check out www.imaginefx.co.uk for lots of "workshops" (tutorials) on digital fantasy, manga, Sci-Fi , etc painting. They also have a forum. I used to buy the mag but now just read it at the shop and the tutorials online.
Mostly I have piles of brainstorming sketches and less fully finished stuff. I wish I had the desire to finish all my sketches into complete works... here's some of the piles
first a few Toy Riot skateboard deck designs I never got around to releasing (yet.. lol) You can see I taught myself to draw as a kid looking at Pushead/Metallica/Zorlac 80's skateboard art...
yes i actually did. i used nasa images as stock to make the planets. however, in the first piece, the wormhole is completely made from scratch with no stock photos. the second piece does use some cloud picture stock to make the nebula.
