I think you did a pretty good job, but I highly recommend using a reference when trying to tackle a project like this as some of the proportions seem a little off. Having the hair not lay so flat on the neck would help add some excitement to this nice piece. I love the steam coming out of his nose, a nice touch. Thanks for sharing.
I have horses out side that I used as references. I drew them with a pencil, then I redrew and coloured online. I dont like using online references due to having to get promission to use the picture as reference first.
And thank you ^_^
