Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I love the colors for the shinys, not so much for the normal one. The pink is too close to beige. I almost mistook it for a brown. The head imo is a little too big, and is un-proportional to the rest of the body.
I just think that your shiny colors are too awkward for a strong water pokemon. Perhaps making the stripes and antenna end a red and the skin color a darker blue would work better. Just my opinion though. :)
