Always wanted to try those shifters; they sound pretty interesting. For a parts-bin build, it looks mostly cohesive. Didn't notice the ring thing until you pointed it out. I'm sure I'm guilty of worse atrocities.
But christ, that's one ugly RD! I'm pretty heavily biased against the overstyled appearance of all the modern Alien-vs-Predator-looking parts, though. It reminds me of around the year 2000 when the BMW car line all went from being sharp, businesslike designs to being beaten to a pulp by the ugly stick.
