I think you've got a strong design coming up here. I agree that on this particular board you might have a few too many statements happening. The big rotary encoder works for me, but the top right blocker needs to go in my opinion, even a logo wouldn't look right. I would also given heavy consideration to returning the winkey and some consideration to removing the arrow blocker.
In short, I think it would look more balanced with the rotary encoder with no blockers, but there is a priority level to which blockers I would lose (starting with the top right and ending with the arrow blocker).
Just my opinion obviously which is going to be biased with my personal tastes. GLWIC!
