Animal Studies 1

I've been doing a lot of animal studies from random reference photos lately so thought i throw a few of my favourites together and upload them. Just trying to get myself used to a variety of animal anatomy and features. Some of them are straight reference studies but with a lot of them i just did a sketch and came back to do the shading afterwards without the refernce image. I find this really helps to make me think hard about what the different features are doing and how they would be lit.
