Generic head practice

Practicing head construction but having trouble placing the features mainly the eyes are small when I draw them, like they look proportional to the face but when it comes to drawing it becomes messy with the pencil and I can't the iris and pupil with enough space and the mouth looks to far from the other features because I understand the mouth is supposed to align with the mouth or is my jaw too low?

Having a hard time with getting the fore/mid grounds looking right. Cannot draw grass for the life of me, and the telescope looks off, I'd appreciate any help!

I'm really struggling with the features and the head. It felt like something is off here especially the 3/4th head.

Fancy Dwarf Guy

This started out as a practice in unique head shapes and turning them in space, but it turned into a dwarf guy in a bow tie. Is the perspective working out? Any other thoughts? Thanks
