XD hahahaha thats more than helpful!!! but i draw on a laptop with no mouse and its hard using that touch pad with my fingers cuz it comes out crooked and im new to photoshop. Do you use a pen tablet by any chance to get it looking so good?
Yes, and no. It's really dependent on your preference as an artist. Some people can make wonders with just a normal tablet (intuos or bamboo or any of the other off brands). Some people can actually do awesome stuff with screen tablets (Cintiq or a tablet PC).
I'd say try to find a cheapish normal tablet for now (either a wacom or some sort of off brand tablet) just to test the waters. If you feel you'll want to draw directly rather than have to use a normal tablet, then try giving a tablet pc or a cintiq a try. More preferably if you're tight on cash go for a tablet PC. Cintiq's are very expensive (the 13HD one they have out right now is $1000), and well....yeah, very expensive.
