Inquisitor on mechanical steed - lenses painted

I'm sorry for the lack of updates. I managed to catch a cold (in Greece, in the midle of summer...) and I had to take a small break from painting. I did some work today and folowing some advice I got about adding a few bright details to break up the overal dark tone of the model, I painted the targeting lenses of the psycannon and the horse's eyes bright yellow. I'd like your oppinion on that as I'm thinking of adding a final, almost pure white, highlight to these parts.
