These are interesting concepts. I am afraid that it will be hard to commit to such abstract designs, but they are cool.
Please change the color scheme. The yellow/brownish/light green color is kind of "puke", and the darker blue/green color says "Florida retirement home." I hope these analogies are understandable - please let us know if they're not, and we can clarify.
#62 is well drawn, although if I am a first-time visitor to the site, I might not be clear on what I'm looking at. It almost looks like a side view of a plant (like aloe or pineapple) growing out of the ground.
#63 was a great idea, but it is simply too busy/crowded. Can you do something simpler for this?
