I'm liking #8 so far--you are on a good track--can you play with it more? Like turn the deer the other direction, maybe make more unique antlers--as far as colors, the multi-colored look you are doing is kind of cool, but I might rather have him one solid color...color isn't too big of a deal, it can be changed later--maybe just play with the direction/antlers--maybe have the text go through him, or over/under him as well as to the side. Maybe take the base he is sitting on away--
Also, though I like the laying down relaxing look, maybe you can try prancing/dancing/jumping as well, something playful.
You are on a good track so far--thanks!
