Sorry for the low rating, but here's your critique.
First of all, let's go over the faces.
I can't tell if you drew noses or not, so I'll leave that alone.
The eyes are a bit too low, and the mouths are too small.
Don't use the circle tool. It doesn't work well on any type of drawing unless you're just doing lineart to draw over
The hair on Victoria looks like it's bulging out on one side and then coming down, and it should be fully hanging down.
Their poses and their tails look stiff, and you may want to work on your paws.
The background looks a bit flat, and grass usually doesn't part in tufts like that.
But believe me, you'll get better. It isn't as bad as what I've seen.
