I do not think the image is appropriate for the gallery. First of all, it is from a tutorial. We want to show off only the best personal work in the gallery. Tutorial files will not be posted (at least, I won't approve any of them). Also, the overall image is incomplete, IMO. The composition is off, the scene feels empty -- something is missing.
I think the model is well done, but it is not gallery material. Keep working at it, and I'm sure you'll produce something that is worthy of representing SM.
