Thanks for the great comments guys, although I can't really take credit for it. Like I said befire, I saw one like this on DeviantArt and being such a simple design, I thought I would make one myself to get back into modelling.
The original did have button eyes, so I may add them as well. A tail would also help to make this my own, rather than a copy, so that too I think.
As soon as I get some work out of the way, I'll get right back to it.
