I can't tell what images you drew and which ones you simply edited (such as the Guan picture). And also a couple of things:
The picture for Rudy's sister, mother, and grandmother are all basically the same drawing, but with slight changes made, but with the same shades of color. They don't seem to stand out from each other in my opinion, and thus are basically clones of each other. I think that they each should get their own distinct drawing with a different posture (like have one of them facing the camera, another looking up, and the other a sort of back view but you can still see the mouth and eyes), as well with different colors and different markings so it's easier to tell apart (such as make Rudy's sister a darker red, mother gray and white, and grandmother pale purple). You don't have to use those ideas; they're just suggestions to make these three characters more distinct from each other and less like clones.
The other thing is the teenage Peaches. You have her with purple eyeliner and purple hair. How is this possible? Considering this is the ice age, make up didn't exactly exist back then. And purple, far as I know, was not a color that cavemen at the time knew how to make (or even knew about for all we know). So Peaches couldn't have gotten make up from the humans. The only way I can see Peaches having purple hair and purple eyes is if she found a lot of berries and "dyed" her fur that color, but it would wash away so she'd have to continuously crush berries for this look.
However, I don't see this lasting too long because I'm sure there are other animals who want to eat those berries and her parents would likely make her stop because her actions are more wasteful than beneficial. Having purple fur would be a disadvantage because she'll be easier to spot. Sorry I just don't agree with Peaches having make up on when it would make her an easier target for predators, her actions would be viewed as wasteful, and not to mention, as I said, make up to this degree did not exist in the Ice Age.
Now one can say "What about the slide in Ice Age 2? The boat? Those weren't invented until later!" But the difference is both the slide and the boat were not manmande, but were part of the environment. The boat was just a large, empty tree trunk that was cracked if I remember correctly and the slide was just ice. Not sure if it was sculpted by Sid or some other animal somehow or melted that way, but it was made from something that existed in the environment around them. Same thing goes for the playroom Manny made in Ice Age 3. Again it was made from things that existed in the environment. Sure I question how they were able to sculpt those shapes, but I'll personally believe that over purple makeup and purple dyed hair. No offense or anything.
