Interesting how this thread developed.
I'm not gonna comment on that topic, I have only one dive experience under my belt, I assume that does not really count.
It was fun and that's all I could say about it.

Yes, there will be a hood.
I'm also working on googles, fins and an aqu lung, including a diving/rescue west.
Unfortunally I first had to remake on of my dresses from scratch, because the mesh was made from triangles and the UV map was unusable for futher texturing, so my time table is slidly off.
I also made two additional textures for the scuba diver suit and I think this package will be online on wednesday this week, followed by the rest of the gear in the next week.
If everthing runs like it should, I will start a new project in the second half of the month. This time I thought about sky diving, to be precise, a wing suit.
