Thanks man, I appreciate the feedback. I also appreciate your care in its wording :)

Now, to your first point, you're right about Minecraft forcing the same texture/model to baby mobs. If I could change it, believe me, I'd jump at the chance. However, due to the themes of the pack being to stay as close to vanilla as possible, I feel that even if I could make new baby mob models, it wouldn't feel much faithful to the game. Maybe I'll make a separate sister pack to Suddlety with different baby mob models and textures for every entity in the game, once I learn how.

To your second point, it again only comes down to the aim of making the subtlest tweaks to pre-existing mobs and their models. I agree that it does look a little bottom heavy, but the shape of the head and snout of the vanilla polar bear was what seemed the least natural, or rather, bear-like to me. I did like your idea to raise the head a little, though. I raised it by just half a pixel, and honestly to me, it did make quite some difference. I've updated the pack already, you can feel free to give me more feedback on it if you want.

Retaining the vanilla feel is what's most important with the pack, so I'm trying to maintain most of the original shape of the mobs, which we're all familiar with. I've had ideas of making wolves bigger, bees smaller, cows, sheep, and pigs having completely different head shapes to match newly-added mobs, and so on, but I've had to restrain myself because it would take too much away from the vanilla game for this pack. I could, of course, make separate packs with these more drastic changes in the future, though. Thanks again!

Thanks a lot man, it is on purpose, I thought it'd look a little friendlier being spelled like this lol
