As most people have already mentioned, you need to scale down the O so it's the same as the rest of the writing. You did a good job choosing a font that will look good with a perfectly circular O, but then scaled the O too big and it lost the uniformity.
If you change the size and it still doesn't clearly read "OCD" to people, then I would reccommend changing the color of just the text to something sharply in contrast with the polisher. Red for instance. That way people don't have to hunt for the meaning as much, they can look at it, see OCD as clear as day, then realize that the O is also a polisher. Since you're doing this for a website I assume color will not be a problem.
I might also add a plug to the end of the cord. This might be unnecessary after you clean it up, but right now it would help establish what the polisher is.
Clever idea, I hope the finished product turns out well.
