I like this a lot! You have a very strong style: nothing about the picture is heavy-handed or overdone. The colors compliment each other well (no one aspect blares) and the subtle shading gives the figures a nice unity. The bodies are well-proportioned, particularly Supergirl in her fine, slightly foreshortened action pose. Foreshortening can often look forced and awkward, but this is effortless! I like the placement of Batgirl's hands... good economic indication of struggle without a lot of broad thrashing; so much more appropriate to this cute, delicate situation! Thank you for posting! We don't get near enough superheroine tickling scenarios. I hope you plan more! Some orginal characters would be nice, too!
