I've tried to make some changes to the rhino I posted earlier, but it's hard. I'm new to designing my own models, this rhino was actually my second decent model. I tried to make the flap that makes the head smaller, but then all precreases did't align. So I've no clue how to get it better. It still has no belly, the back gets higher instead. And the hindlegs get to long.
I did managed to make another model from the same base. Using some flaps that form the big horn to produce a wolfs head. here it is:

Any advice on how to change the proportions of my rhino would be appreciated. When I make a model, I just start folding and then see where it gets me. I don't start from a cp, I just start folding and hope for the best haha.
