Well, first of all, I think you are doing yourself down - having looked at the post in your gallery
http://www.drawspace.com/forums/index.php?...i&img=41187 your drawing skills don't look "horrible" to me.
Course of action:
- get yourself a sketchbook, draw all the time - any time you are sitting around - in a cafe, on a bus or train, watching tv, etc
- work through Brenda's lessons here on the site.
- post more work here, post work for constructive critique. Join in on the forums.
- there are basically two approaches to drawing figures - constructive and observational. Constructive is typified by books by Bridgeman
http://www.amazon.com/Bridgmans-Complete-G...e/dp/0806930152 and by Loomis (Loomis is not in print, but easily found online).
http://acid.noobgrinder.com/Loomis/Observational is typified by Tony Ryder and David Kassan - see Tony Ryder's book on Amazon
http://www.amazon.com/Artists-Complete-Gui...g/dp/0823003035, and see the demos section of David Kassan's website.
http://www.davidkassan.com/instruction.shtml- while Drawspace is great, for gaming art you really should also become a member at conceptart.org too, and get actively involved there, as well.
- also - now you've posted - take advantage of the resources and people here and elsewhere - so often, I see people posting messages like yours, who then go back into "lurk" mode instead of continuing dialogue and discussion and making active use of the contacts they've just made.
