To be honest, I actually really like the "spotted" look you have going on! And the seem to really catch the light in the vid in your sig! You remind me of the fish from the book The Rainbow Fish (: Anyone else love that book as a kid?

(hard to tell in the pic but the speckly-looking scales are actually shiny/sparkly).

I think my next tail may be a sequin tail

I think you could modify the fluke without having to change the rest of the tail if that's what you decide you want to go for.
