I have a Tablet PC so I'm drawing on the screen. It was a quick sketch hence how unclean it is but if you see the other two new works I posted you can tell I'm learning the program.
as far as dedication goes, I think that will be for writing. but who knows... if my sketches become good, buying a tablet would be the next logical step
If you do I suggest jumping in and getting a tablet pc. I got one around 700 on clearance. It's a laptop so i don't have to only use it for art. I use to use it as my main pc. Then I realized that it's more valuable if I don't kill it trying to run games.
