Very nice, from the style, color, contrast, the general positioning of people and objects; this is well done. However it is not without its flaws, for one Lucy looks too...eh...curvy? I'm not sure, it could be that her shading isn't dark enough but it's strange. Mike's and Lucy's fur on their chests' also look over exaggerated, and Mike's hair (fur on top of his head) has an awkward line that doesn't look like it knows where it needs to be; on Mike's head or apart of his head. This last one can be solved the same way as the first, just use less exaggerated fur. The last critique I have is Mike's blush, now it fits and is lovely, but the black lines are a little too pixel-y. Although that can't really be helped, considering it's drawn in MS paint.
This is my review of your drawing, I mean no offense b any of it, I really do love your style.
