Sulfur spike retexture.

The sulfur spike looks a bit weird with a relatively solid yellow texture
Sulfur actually has quite a bit of light sheen on it which makes it look like it has white or glassy hues on it.

This could be reflexted with the sulfur spikes tips having a lighter gradient going from top to bottom.

The sort of solid color works ok with  pointer dripstone, but with sulfur spikes it really stands out to me.
