I've got PixelProspector in my subscriptions on YouTube, and was excited when I saw the game featured there.  Keep up the great work!

The nose definitely pops out at you more than anything else.  Below that, though, it looks like he has four lips, though I'm assuming the bottom two are a double chin...  A tad more detail there wouldn't hurt, even if you want him fading out.  Probably on purpose, but your one in the signature is backwards.  But, like I said, that was probably done on purpose.  Overall great piece!

I like it, but more detail would be nice!
Great to see some dump threads, too, so we can pick through everything and look at a lot of your work!

To me, the rocks on the bottom look more like waves than rocks, which wouldn't make too much sense under water.  The shape of the circular rocks is more readable, and I think they'd work better than what you currently have.  If you're trying to make stalactites and stalagmites, then there should be much less of them.
