Nice hair and face model! A few things that could be improved to me are the eyes, eyebrows, and glasses. The eye whites look too grainy that I'm not sure if its supposed to be veins or something else. The brows look like they were texture painted rather than being hairy. For the glasses, the front frame looks too flat. Maybe add a bit of beveling to make them look curved so that light can shine one side? Other than these things, he looks pretty good!

Nice model! Though his shoes look unusually boxy, especially at the front. Other than that, its good!

Hiya, I'm just going to be proving feedback for the bear and the gloves. For the bear, a background would be nice so that the white parts like the ears and the mouth don't blend in as much. The nose could be sticking out as a plastic bit or as a piece of fabric. Since you are going for a plush look, you could give it a knitted or plush look to it. I'm not too sure of how to make a plush texture but for yarn, a displacement map should be fine. If you aren't sure of where to find a yarn displacement map, let me know! For the gloves, if they are going to be cartoony looking then I would say the texture is fine but if you are going for realism, some scratches would be good. The fingers look like they are separate from the base of the glove rather than attached to it. However that might just be me but if you see what I mean, then I can help you out with trying to make it look like the fingers are "welded" to the glove. Other than that, nice models and nice detailing/colors!
