Updated this picture with some minor addition to details, and also the most obvious addition were the bubbles coming out of Ahsoka's mask here. And added the Clone Wars logo in blue since that's what the color of the logo's season 4 is like.
Ahsoka in scuba gear, ever since I saw the very brief moment of her on that gear on the preview, I thought of drawing it. I doubt I got the design correct since all I could find were extremely small and blurry images, but It looks good enough to me. Oh, and the bubbles I did it by following this tutorial [link]
