Did you ever actually go diving? Because there are some mistakes in your picture:
1) Have fun using pure O2 on a dive - will kill you at ~6m down.
2) How warm is that pool water supposed to be?
3) If you were no suit and are skinny you dont need any weight.
4) The BC(D) looks weird to me.
5) Pressure gauge goes on the left. (atleast here)
Other than that nice

I haven't never dive. I haven't any exact knowledge about it. I'm just a kind of fan 
Thank you for the corrections
I would be very happy if you explain the 1,2,3 and 4 point. Why? And how does it work?

You should try .. ^^ I got some underwater photos in my gallery if you want to see them
1) Oxygen gets poisonous under higher pressure. The higher the percentage of oxygen in the mix, the earlier. 100% kills you at about 6m. normal air (21%) is fine with over 50m i think though than you get nitrogen narkosis wich appears when there is too much nitrogen in your blood. appears if you dive with normal air under ~30m. thats why recreational diving limit is 40m very short ground times anyway.
2) Water drains away your body heat 1.000 times faster than air does, so if the pool isnt heated to somewhere over 30°C it would get cold rather quickly. So even in a pool most people use Shorty wetsuits. If colder than 25°C Steamers with varying thickness depending on fit and activity.
3) The main thing that adds bouyancy to you are the suits. As your body is made up from about 80% water it doesnt affect it so much and the tank is enough to keep you down. i'm speaking from experience here ... on my explore scuba diving dive i wore only shorty and needed no weight. When you wear a suit though it adds alot of buoyancy ... a 7mm steamer can add well up to 6kg depending on the size.
4) Most Buoyancy Compensators/Buoyancy Compensation Devices are like a jacket (reason for being called jacket too) they usually go around your sides and infront of you too. There are wingjackets, which inflate only on your back to the sides, but you would see that on the sides then. On my pics you can see what I mean.
If you want to know more send me a note
