I love it! I think you should change #4's blend of colors because it doesn't go well together. The eye color for #5 looks like it is part of her coat while the others don't. I think you should make their head fur a little bit straighter and not as curly. #3 should probably not have a sudden white after the blue and brown. it does not match with the other two. So basically you just need to blend the colors a bit more. I love the shape and style. You should make the cheek fur a little less curly too. Otherwise, It is amazing! Way better than what i can do!
thank you so much for the thoughtful critique
