Isaiah's Koi

Doing this one on wed night (outline and shading anyways) will be full color, and it is covering up an old tattoo.
the background (bamboo, waves etc.) will be mostly black and grey. i am planning on doing the peony a very deep purple and magenta to contrast the koi, and the cherry blossums in traditional format.

any thoughts?
