i'll post some samples of what i've been doing if it helps (if there's some other info you need that'd help just ask!) i've been coloring sketches with photoshop CS4, and i kinda want something i can easily draw with from start to finish.
lately, i'll draw the main subject of a pic as a sketch, scan it, color it, and if i can i'll try to draw a bg with the mouse that i have. ex:


( the first one ain't so great, i know, but i don't have many examples cause it takes a lot of time i don't have to draw bg's in color with a mouse. ; . ; )
being able to do all of this on the computer would make things easier for me. so... any suggestions? are there any important things i should look at or take into account? i'm basically clueless here, so... HELP? ; u ;
