I don't have a problem with the water. I feel that you added your own flavor to the painting. It has a more impressionistic touch. When waves crash, they do tend to curve a bit, but I'm not one to nit-pick over details and write a whole novel about what a painting should or shouldn't do.
The water is not acting like water but rather more like brushed/sprayed paint. It should look more misted where it is spraying everywhere. Your clouds have little form. That's good in some places, especially the distance. It works on the left where it appears more dispersed but not so much on the right. The structure pieces on the right look more slapped on rather than placed in the scene. They all appear practically on the same plane with little change in size, focus, and color to create the illusion of depth. The waves on the right all appear on the same plane and create no illusion of depth. There is very little variation in them. Your light sources appear to be all over the place. There is no light dispersion/saturation in your water. With how bright your sky is, the scene looks very dark. Less black is more. Get away from black and use dark colors from the scene. Watch your bounce light and use it more. You asked for critique in Crimson Daggers, so I hope these things help. I don't claim to have them all mastered myself and am growing as well, so I am sure there are others who could critique this even better.
Here via Daggers. I simply love it. I don't honestly know how to tell you to improve other than maybe the left of the image around the monsters arm the dripping water looks a little less focused compared to the rest. But that's honestly me trying to pick something to crit about. Also there's no real clear light sauce for this piece. But I wouldn't change it unless you really wanted to render it up more. But I think it's a fantastic concept piece ~ in my opinion
