As far as cool looks, it's a winner.
As far as manufacturability and efficiency, it could be further optimized:
1. Hex holes must be broached, round ones can be drilled. Unless you require a hexagonal hole, use round. (But, those hex holes in the spokes DO look cool)
2. The ring surrounding the axle area (that has those oblong slots in it) serves lettle purpose aside from adding weight. To understand why, imagine the metal 'spoke' if that ring wasn't there - it would go from the central hub to the outer rim. The ring might be distributing forces very slightly across the spokes, but not enough to make any difference. Instead beef up the center hub a little bit (thinnest area about 3/8-1/2 inch) and lengthen the spokes to fit.
3. Ease the edges of the spokes a bit.

How thick are the spokes? To me it seems you could get away with them being about half as thick.

Agreed and why not make the hub smaller if your going live?

On these wheels (the one under the one standing up), there is a mini hub instead of a lightening pattern around the hub. Try it out in CAD and see if you lose more weight that way.

I agree with RC here. If you are going to drive it with a live axle, your interior hub can be smaller, those 5 interior slots can be omitted, and your spokes can all be longer.

Keep up the good work. It takes guts to put your design out here to be critiqued. Good job.
