Both are interesting but they don't feel complete IMHO. Love the idea it just needs some tweeking.
The first one could use a different crop. The heavily blurred light/dust at the top is distracting from the fun in focus area towards the bottom.
The second one holds my attention longer, mostly because of the edge of a circle that is on the bottom. I would love to see more of that circle in the shot. It adds a nice splash of color that isn't overpowering.
