What's boring about a perfectly detailed low poly hand? It only goes to show me that Dan can pull off some great quality models with half the poly count that someone else might had needed. When i first saw that pic, i didn't thought it would be anything under 1000, so i'm really impressed.
Keep in mind this is a first person model which will be carrying a gun which adds more polygons to the sum. Since this model will be rendered at all times, one can never be too concerned about the poly count.
@Dan, just make sure the hand looks properly on a top down view(about where the eyes would have been) cause this is the only view the player is going to have on this model. The arms from some other hand models i've used before looked too squarish from that perspective, so that's pretty much all i'm worried about.
Cheers,
Aris
ps: if you want to track down how this model actually looks in-game, keep an eye for the Intense Ai demo that's coming up.
