amalthealuchiaroseaizen participated in my brief journal for free artistic freedom characters. Her three colors were emerald, silver and gold.
Notes on this gal that I thought of while designing her. Please don't feel obligated to keep the small details I added. They're just for fun :3
Look into perspective. One point perspective especially. This gives your the feeling of foreshortening as things lessen into the background. Also buy a four-legged animal toy that can be stood in the angle you like. Practice the pose within perspective points and you will see it given depth, which translates that 3D feeling.
Side thought, try varying the thickness of your lines at the ends, it can give the feeling of a pen pressure and flows. Uniform lines can feel static. I guess you are using Sai or FireAlpaca?

A nice start on a new creature. You have potential to grow the more you explore and create like this. Perhaps make a sheet with a character turn around, showing the other angles of your creature, and a few action shots of these abilities. This will bring depth into her as a fully formed character and also allow you to give a life to the character. Even a few emotion faces can show what personality she may contain.
I bet this community sees great things from you.
