He already has a name, its Todd! And as for breed he is really generic, which is nice as people can decide and it also means that he can be any colour and a breed can be easily assigned. He has typical pony features and because it is just the headstudy, it makes it less strict on what his breed could be.
Please excuse the photos in this post though, unfortunately I am unable to download photos off of my SLR camera at this point in time and so this means that I have been having to use my phone's camera! It is 5 megapixels though so it is ok... This is Todd after just a couple of hours, where I developed the head's shape and put some structural features in place.
