I generally advice against using 'smeary grey' reflection maps, but I'm going to include a few fro examples. This one may look fine to you, but it may not. To me, it looks fake. The thing is, even if it doesn't look fake to you, if the ones above don't look fake either, logic dictates that it would be better to go with the ones that don't look fake to anyone over the ones that look fake to some and not others.
