Wish I'd known how to use photoshop effectively, that would have saved me loads of time. So many life-saving short cuts!
I still wish I knew how to produce something to a very high quality. I would like to make merchandise, but have no idea where to begin. If it ever comes to printing god help me because most of my pages are of such awful quality that I'd have to make them all again from scratch.
I wish I had read more comics before beginning my own. I'm beginning to worry that my panel layouts are uninspired...Comics are such a flexible art form-- you really can do anything--- and here's me taking no risks because I'm not sure what's possible.
There's still so much to learn...it never ends.
