Your shading is subtle. That isn't always bad, but it can often make an image look flat if it's not used enough.

I suggest texturing the fur so it doesn't look as matte.  You might also consider darkening the areas that represent lighting - increase the contrast and all.

I see what you mean thanks I'll fix it later.

Is not bad, but its right ear (left side for us) looks squared. I sugest to fix it with a better curve.

Furthermore, it will look much better if you complete the drawing.
