Swimsuit Serena and Eureka

Trying some new style here. I'm wondering if I should use the anime style for the heads and keeping everything else. Naturally, this was a pain in the ass to make.

XY/Z never really did have a beach/swimsuit episode. And because of that I could only gleam on what swimsuit Serena wore in the 2nd XY ED, and as there are no concept art of her in the swimsuit that I am aware of, I was forced to base the swimsuit's appearance on moyori's fanart (Japanese artist).
