the most striking thing to me at the moment is obviously the seam in the middle but I assume your on top of that one

It's a really good start I like the detail you've got on the eyebrows that looks great (and better than I've seen on some higher res models! )

I'm not 100% on the face proportions I know you are going for a different look and not normally proportioned, maybe if you put more of a crease between where the bottom of the nose meets the cheek it mite make it sit better.

Doing well mate, keep up the good work.
