Preeeeteh shiny :/
Mabye tone down the shine on it. (Less contrast?)
It looks AMAZING though, I love it 
By shine do you mean the specular highlights on the shell? Or on the fleshy bit of the snail? Or both!? lol
I want to get the wet slimy texture of the snail down, but he (she?) ended up being one gooey blob, and it's lost the slimy scaly texture of the original image. I wonder how I could replicate that sort of texture with the resolution I'm working with?
Anyway, I fixed the shell a bit:

I've highlighted exactly what I've changed here:

The shape of the shell looked a bit funny after looking at it again.
Any suggestions on the flesh texture would be very much appreciated - I'm wondering where I should go from here. Later on I'll get rid of the back outlines more, and I want to do some AA on the shell. Tried it a seconds ago but just made it blurry so I'm going to do more homework on how to do AA first!!
