WIP tileset for a fangame.

My biggest gripe would probably be the pipes. The shading and palette doesn't really match their metallic nature; it should stand out more, be shinier, more saturated - maybe a bit more hue-shift. I'd also recommend making the head stand out more in comparison to the shaft - the shaft is a bit thick, after all.

I like the cave tiles. everything else is pretty okay.

actually, in general a bit more saturation and contrast and hue-shift might help to flesh out the mood.
