Evaluation of the scene:

I am happy with the underwater look I achieved with this animation. I like the swimming movement through the scene but on evaluation I think the last bit of movement is slightly too fast and should be a bit smoother. Also with one of the air bubbles I forgot to make it disappear when it goes above the water so you can see it above the water, I need to change that to improve the scene. I added the pool sinkers to add some more movement to the scene and to give it a bit more going on, It gives it a holiday pool look.

Render improvements:

When I first rendered this scene around the 30th frame the water would go more opaque and dark blue which would look really odd and unrealistic, I could figure out fully what was making this happen so I had to change what I was using for the water. When I changed the water it stayed the same colour the whole way through the animation. The new water was slightly less reflective though which made it look slightly less realistic but overall it looked better as it stayed a consistent colour throughout the animation.
