My own spin on Rainbow Dash (Second sprite, constructive criticism please!)

[Gors]

the problem is that you make it look like a cat when.... it's a dog-like animal.

the red patterns on its face doesn't follow the curve of its snout, making it terribly flat. Also the lack of shading helps making it even flatter in that respect.

Do not use MS Paint default colors and/or tools like circle shapes or lines, they are generally ugly and should be avoided.

finally aside from being a white cub with red details, it doesn't look like chibiterasu at all.
