One Night Under the Moon

First of all, I think the drawing in its entity is really good and shows a great experience. And I love the style.
But the white lining on the cats' bodies feel pretty odd to me, mainly because it's nighttime. When you do this, you should blend the character's color and the white you gave to the lining. The cats almost look like they are shining from inside. If that is the impression you wanted to give, you could have subtly given a small touch of light at the outside of their bodies. I think you still did well. Light is tough to handle carefully. Which bring us to the light rays.
The moon's light there is supposed to have in this scene would benefit from being separated more or less equality between the characters and the background.
If you want the cats to be more enlightened than the rest of the scene, do it with a small light that you blent to the rest of the darkness around them. And even if the moon is full, the contrast between shade of the trees (I can understand that trees give shade to the picture, but not that much) and the lighten part.

Hope I helped you,

P.S.: I don't really understand the star system. You get all 5 stars everywhere.
