not feeling it, the lighting is all over the place and there is no real focal point like jjfreight said.
spread the lighting out a bit more, make it bigger, and make the circle of it less visible basically, dont brush on the sig, get a large soft brush and click off the sig, and some light will go on it, if that makes sense also, i think the wireframe works only in some places you should delete most of it. i think the overal tag is ok, it could use a little work as statted htough
There's no real flow, there isn't a focal point, and I don't think the wireframe fits in very well. Work on all that and it would look pretty good.
