Nice one, its a great tutorial to be following. Produces nice quick satisfying results
One thing I notice is on the back legs theres a ridge running along the top front. If thats there intentionally, ignore me. It does add a little more dimension legs. If its just an artifact of using the split poly tool just be wary of it. I've found my personal preference to be add a line running where i want to go then to smooth out that line before running into the next. Helps to keep my fustration levels down!
