Well, the thing is that until recently, although I'd been more than happy to colour 'till the cows come home on the screen, drawing and inking just hasn't come quite as easily. I've tried inking in Photoshop, Painter and even Illustrator and, although that was better it still didn't come anywhere near the feel and flexibility I got with using a brush. That was until I found Manga Studio.
Hot dang! The pressure and quality of the line really does feel (well, to me at least) and look right. So I'm convinced. It's speeded me up and I'm getting the results I want. Well, apart from it not making me actually draw better. Only cups of tea and biscuits can do that.
Here's a page from my Pulsar Crash strip from the new Smart Bomb. Multiple layers also let me do colour holds really easily so if you see some lines overlapping, that's what's happening there.
