Is my art just too intellectual for you guys?

In my case, I rarely poke my nose in here, but...
The first one is interesting. It would make a great "re-entry" effect for the space shuttles.
The second pair, the one on the left is intricate, and you could probably spend hours looking at it just studying the conture effect. The one on the right is soothing, like something a dentists should have hanging on the ceiling over "the chair". Seriously, that would be coool
#3 looks a lot like those photomicrographs of a thin section of a meteor, taken through a polarized lense. Always interesting to see how the crystals lock together. Nice colors, too.
The last one looks like the reflection of a really big flower in the water. I'd habe to say it's a draw between #1, #2 left, and #3, the "polarized light" one.
