The roughed Aluminium looks good for this. Only thing I would suggest is the replacement of your decorative hex holes with round holes. This would save a lot of manufacturing time.

Looks good, sort of a prehistoric ice cave themed look? (mabye its just the render lighting...)

If you are planning to use dead axles, the wheel has to have bearings that fit into it so it can be driven, which means you either have to somehow find a ball bearing with a hex outside shape. Or find a bushing in the shape of a hex shape externally and put a ball bearing inside of that which doesn't make sense as bushings sort of work like bearings.

If you are planning on driving the axles, you are fine.

Direct drive wheels aka live axles (which your wheel looks like it is made for as there is no mounting hole for a sprocket) you are fine as you are.

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.

Eliminate the external radius on the hub. External radii are the best way to make your machinist hate you. Everyone loves them because they look cool but you need a special tool to do it and it takes time. If you really want a non-square edge, chamfers are much better.

Re: pic: Wheel Idea 2

Ok, Here are a list of things that I could improve upon that I have taken from everything that has been said.

1. Switch from hex to circles. (Would it be better to go for a keyway circle? Or keep the hex on the drive? )

2.Trash the outside ring on the hub and make the spoke longer.

3. Take off the fillet on the hub.

4. Take off some of the width on the spokes.

If I have left anything out or am misinterpreting things, please, do not hesitate to correct me.

Rion if you ever get some time. Send the wheel over to me and I'll take a look at it. I'll be able to give you detailed explanation of things.
