Oh man, I so couldn't figure out Manga Studio (& that was MS4, I think, which came with the intuos4, maybe? it was ages ago) but for just illustration things, you should check out sketchbook pro! (by autodesk) you can test a month for 3$ which is pretty great. they have great markers, perspective tools, flipbooks for animation & symmetry tools *__*

Lineless painting totally takes F O R E V E R but maybe that's just cuz I'm a n00b, too? I imagine it gets easier. Layers, though. So many layers!

Anyhoo, I would ttly follow your comic if you post one!
