>>39140280>>39140330>>39140462>>39140535I'm a genuine fan of your designs. Here are some critiques. The xeno needs a little tlc, and the tail should be changed. You have all these "sharp" cone like shapes but then random spheres. Could go for something a bit more unique and alien.
The disc thrower is great, but the cylinders may look better as more jagged shapes. They look just glued on. Also I'd suggest darkening the skin tone slightly to fit the rock typing. Wondering if the rock on its back is just another disc for throwing? Otherwise it's a sound design, which is rare for a humanoid Pokemon.
Grassbat is amazing as is. Like you said spidercrab would make a good UB, can't really complain about it.
