My sketches:

I originally drew them horizontal, but then learned they were vertical images so I had to redesign them slightly.

This one is my favorite.

I like this idea the best because I feel it gets the message across well and I like the image itself.

This one is my least favorite.

I like this the least because I feel it does not get the message across as well as the others.  The design itself does not feel like something I want to spend a great amount of time on either.

This is my 2nd favorite.

I like this one as well.  I think it gets the message across while being fun to look at.

Here is the final piece!
