Skeletal/muscle structure would be lovely, but you know what most people overlook? The center of gravity. How a creature balances when it's moving is damn important; look at a giraffe run, for example. Maybe some detail on how more obscure anatomical quirks could evolve? (I'm looking at you, anglerfish.) And, if you think you're up to it, maybe the effects of higher and lower gravity on the structure of muscle mass. Ah, if only I could draw what I see in my head. >_>
I'd be interested in skeletal structure. Especially points on the body where the bone is more likely to show on a general design. XD Those little indications of bone under the skin add so much life and believability to a sketch for me.
I consider that to be more of a detail that lends to the personality of a species than straight up anatomy.
You have a lot of ideas already and I don't have much to offer but I love the sounds of it already! I have no problems coming up with ideas, it's trying to construct them in a believable way I have trouble with so I really like the ideas you have. I hope you'll look at a few different anatomies, particularly creatures with more than a few limbs? I find making them believable is the hardest.
More about the creative concept about thinking up fictional creature, what is good design? what is bad? for what purposes good bad etc? Or how you go about making fictional creatuers. I don't know, that is why i need such a book.
Wish I had time to read all of these...but it's late and I need sleep.
So, my thoughts (probably repeating what others have said, but count it as a vote )...What I really want to see is how you create alien physiologies that are so believable. So, how to take pieces of anatomy and blend them together; how to layer the skin onto the muscle onto the bone to make it real; how to give an expressive face to an alien monster.
I'll buy it if and when I can. I recently got Mostly Creatures, so it might take a while.
Man, that's a really tough one...Not because it's hard to come up with ideas for possible approaches (that's the easy part!), but because it's so subjective and dependent upon the individual artists' strengths and level of interest. Personally if I was ever to attempt a book like that I would focus on phyletic relationships and deriving ideas from speciation, specialization, convergence, etc. But that's a totally different creative vibe than I get from your work. To me your strength and brilliance lies in your ability to distort and manipulate and "mesh" anatomy, disparate anatomical features, into cohesive creatures with a great gestural sense of rhythm to them...I mean, if there's one "take-away" lesson I've gotten or aspect of your work I've tried to emulate, it's that. So maybe an exploration and exposition of how you achieve that effect, if it's something you can pin down and articulate yourself. Um...Hmm, I'll have to think about it more, but yeah, that's my initial impression. "Living tissue as organic Play-Doh," somebody once said to me, and that's exactly the way I see your stuff!
