I just attempted to make a webcomic in photoshop, screwed it up, and tried again in sai with the same results. There's too many little things I rely on heavily that only Flash seems to have. Most notably, resizing/transforming something in photoshop or SAI makes it look pixelated and ugly, as does zooming in on it. Isn't that what vector art is all about?
I have always drawn overtop of a scanned and imported sketch, but I still have to resize, drag, twist and stretch every single thing I draw a dozen times before it looks right. I also rely heavily on being able to recolor something with only a single click or two. Is there no way to make flood-fill work in these programs like it does in Flash? Coloring by hand might be the right way, but it aggravates my carpal tunnel too quickly.
Lines in general look to soft in these programs, actually, no matter how I configure them.
What other drawing programs could I try?
