Did you choose a base with bigb bo0bs on pupose? XD Sorry, had to say it.
The green spots hurt my eyes, but I like the rest. As sor the glasses issue, all you had to do was dither some whitish blue in the sorner for some shine; you don't need semi-transparency. Actually, unless those are sunglasses, it wouldn't look like real glasses; as a glasses-wearer, I know. XD It would be a bad thing if regular glasses were tinted, especially in a dark room.
