Hello, TheRealAkito,
I didn't think your advice was bad at all. I had my suspicions about the dome but you've confirmed my suspicions.
So, I fixed the dome. I darkened the lips. I tried for some reflection in the glass dome (to simulate glass), I reshaped the little guy under the dome too.
I find the octopus looks a lot better than the little dude, still some work to be done there I would think.
I tweaked the colors some more too.
