Takama-Gahara here, I have for you a question. How draw good dergs?
Oh I’ve got you covered:
and there you have your F E R O C I O U S B E A S T
But in all seriousness, instructing people on how to draw imaginary creatures is a bit hard, for me at least. A lot of my learning process is based on winging it until it looks okay and makes even a little sense anatomically. I try to look at animals like birds, bats, reptiles, dogs and horses and combine traits of their anatomy into some sort of a mess of a creature. So I’d instruct you to simply start with looking into basic animal anatomy and trying to learn how animals actually work.
There are tons of tutorials that are way better at explaining things than I’ll ever be and they can get you started. Back in my day when I started drawing I was inspired by Todd Lockwood and his art. His creations gave me a good base to start building my art from. I studied the way he drew and shamelessly copied parts of his work until I felt comfortable enough to draw and try different things on my own.
Not being too ambitious when you start out is pretty important, do some simple designs, kinda like the drawing above. Just drawing some simple lizards with bat wings is a good enough start! And remember to practice, practice and practice some moreヾ(´▽｀;)ゝ
