I think this one would be better if there was a light rectangle behind the rectangles and circle on the right.

I really like the balance of this one. Most elements muted, but a couple brash. The eye really moves around it.

Again, strong balance, and a good path for the eye to follow.

This one strikes me as fun, fresh, and funky.

I’m still not sure what I think…

I think this one could be more interesting with one of the arrows upside down.

This might be my least favourite. There is nothing dynamic about it.
