I really like these, overall they are quite readable and in an rpg setting they would get a little bit of explanation so I don't think anyone will have any trouble seeing what they are.

I think they would look really cool if you added a shining animation to them. Nothing too major, just a little bit of sparkle every once in a while.

Good job! :D

 This is great! the animation is a little bit jerky but the detail is impressive. Try tweening the animation a bit more!

 This is great! I like the preview... it seems to add to the idea.

Great color choice too, just enough red.

btw the snail one is for fist bumping. The second person make a peace sign (thumb down, hand parallel to the ground) and slides his hand under the fist of the person attempting to fist bump.  SNAIL! :p

Good luck in the challenge, seems to me like you have a good chance of winning
