Tropical beach anyone ?

Here are my original characters Vanae and Reena playing in the southern sea. They're really getting into it even though it's just a silly ball game.
And they have weird tan lines because they usually wear weird clothes ^^.

The scenery is strongly influenced by some beach I visited in Okinawa which was fabulous. I really wanted to give the "tropical" feeling. Also I wanted to show that there were absolutely no waves at all on this beach but here the sea is a bit too mirror-ish for me, meh.
