Help Me Pick the Cover!

The artist just sent me three final drawings for the cover! I need to pick the one that communicates the excitement, enthusiasm, and fun of locum tenens! Please help! Which picture is right for the cover? Which one grabs you? The one on the left (1), middle (2), or on the right (3)? I've got a favorite, but I'd like to know yours. Please respond with your choice! Thank you so much.
