False. I do most of my work in Photoshop, despite the fact that I still use AI. Although PS' main function isn't art, you can still make some spiffy stuff in it if you know what you're doing.I can't help much with anatomy (because mine is crap for people) but I've been working out plans for a series of value/coloring tutorials, if that helps.
I can give advice for anatomy in general, however.
- trace photos. Yes, trace them. But only for practice, don't post them online. But tracing photos helps immensely when you're starting out.
- if you want digital, invest in a tablet. Wacom makes incredible products; I've been using them for all six years of my art.
- use references when you're doing a piece you want to publish. "But lark i think i get it" shut. Use references. Trust me, you don't get it, and you will heck up the anatomy. I make this mistake all the time.
- try to draw a variety of creatures, don't just focus on people, a specific animal, etc. Another mistake I made.
- don't try to develop a style right off the bat. Yours will come. Anatomy is more important.
Coloring things
- start out in black and white to get values down. I found a tutorial for coloring that I use when I do this, and I'll post it here eventually.
- NEVER shade in black. God, this looks absolutely terrible. Use colors from your background. Trust me, it looks sooo much nicer.
- on that same note, don't use pure white either.
On a side note, if you notice something you don't like about an image, fix it right off the bat. Don't wait around because it might be unfixable later.
