No not pro, I work too slow and stuck in full time job already

Originally I was looking at ur sprite on my phone which is why I thought it was all red. Since then I can see it has browns.
Note what I did with the shading on the fur, the lightest colour uses a different hue. It's good to use a mix of hues in ur ramps.
I think a different colour underneath and maybe the tail too is a good idea, such as the white u have now.
especially if u plan to make him tilt up and down aas the colour provides a visual signal whether he's in fall or glide mode.
Generally in pixel art we avoid or reduce the use pure black/white though as it seems a bit unnatural.
normally I would have worked over the outline to make it more selective.
