I liked the composition of the original. The two problems that I saw were the large amount of sediment in the water and the color balance, so that's what I fixed.
Remove the larger sediment with...
Filter - Noise - Dust and Scratches... (radius = 2pixels, threshold = 6levels)
Remove the smaller dust noise with Neat Image (auto settings)
Adjust the colors of the result with...
New Adjustment Layer - Curves (click auto, then use the midpoint color balance dropper to find a neutral gray off the mask)
New Adjustment Layer - Hue/Saturation (saturation +35 only for the reds in the suit)
New Adjustment Layer - Curves (made a linear shift to brighten the midtones and compress the long highlights tail)
