If this orange mob is supposed to look like a tongue, maybe You should make it more pink and flesh-looking. You could also add this sinew under the tongue or something like this.
I think these white things in the orange guy look like mouths. If so, maybe You could make it easier to reckognize, for example adding teeth, tongues (hehe), because it looks like eyes from Terraria for now. 
The orangey flesh is intended. It's supposed to make him look more earthy looking. He's not exactly a tongue, just bumpy like one.
and yeah, they're supposed to be mouths. The white is the teeth, and pink the interior of the mouth. I was unsure how to make the teeth seem separated with such a small color pallet, so I stuck to something simple. I'll try to make them a bit more defined. I think animating the mouths will help a lot with that, though.
Keep practicing, and have a good day!
Hey tsej! I happened to read your other post while at work today, but was unable to reply. Not sure why you edited it out. . .
The trees could definitely use some more definition within the branch layers. Admittedly, I kind of rushed through them. haha
