That would be extremely ineffective in terms of aiming. Not to mention the knock back.
Well, the shading is rather flat. Thats the biggest problem. Other than that, its just the design. Pachirisu's in general don't have such an ovular head, it's more circular. The ears are also thicker, and are shaped like like four-sided pyramids. The spiky fur in the tail is also supposed to be bigger. Not much else to say, but yeah, it's really the shading that brings it down.
That's a problem I already see. It's hard to make them look like them without hteir armor or defining traits, so I had to pick which would I prefer: Make it look like a generic Pokemon gijinka, or try to style it after the versions in the RP. Since I chose the latter, they dont look much like their pokemon counterparts. The head and eye proportion is actually just my style. If you look through my gallery, you'll that all my recent humanoids are like that. As far the clothing goes, yeah, it was hard to do, and I still dont have the complete hang of it.
