my favorite is the 2nd one

I'm another fan of the 2nd one!! The pinkie pose looks great with the web stretching over to it. The other finger's webs would look nice if they were blended into the sides of the fingers. The 'hard outlining' of both sides of the fingers prevents that. This pic shows what I'm talking about: the web between the 1st & 2nd fingers

I'd love to see more webbed hand poses, & webbed toes, too!! Your aquatic artwork is amongst the best!!
