Ditto with this pic! In some ways it's even better as you've captured some bits of the original animation style for each of the movies these characters were in. Megara's angularity comes through even though not so much to look stylistically different from the others. Everybody looks exactly like they are supposed to be! I'm really impressed!
I ink with a Winsor-Newton Sable series 7 brush. I use two sizes, 2 and 3. I also use rapidoliners for straigh lines on things like buildings or panel borders. I use Black Sumi Ink by Yasutomo. And I listen to music while I ink.
As for learning how to ink I'd suggest picking up 'The Art of Comic Book Inking' by Gary Martin. I believe they are out of print but if you can find them used and in good shape pick them up. They are very worthwhile. That and be sure to ask alot of the inkers here questions. I doubt any would refuse to answer honest questions After all, the greats had to start out somewhere too
