First I think you did well with the exposure time - I like the way the waves are represented.
Second - I think you could get rid of most of the sky (but not all) - it doesn't add much and competes with the waves.
If this makes your aspect ratio too wide you might want to crop a bit from the left and right - but thats dangerous - there are many beautiful colors.
Third- since this is possibly more an abstract than a naturalistic photograph I'd mess with it:
Color, tones, detail - pull the registers to exaggerate the message - the image allows it IMO.
Room to play !
I agree. I'd remove about half the sky - the clouds are interesting and the waves are interesting, but they cause the eye to bounce back and forth. Nicely done!
