Very nice detail and pose...I like the space around and the just off centre is the only cop I think would work in this situation...water splashes in the mouth add...if I was to say anything is a 1 degree CCW rotation...But not sure if that would be too much as it looks like it may just be a half a degree off...And some selective sharpening on the water in and around the mouth to add bit more sparkle to the water ( Really just nit picking)...I like the image as posted...Looks like this guy is quite old and been around for quite a while.
