Skull anatomy practice

I feel like I can't get my line quality where I want it. Also, my proportions are consistently skewed--how can I fix this? Any advice is appreciated.

Practice

I tried making another full page sketch and I would like some feedback on my perspective and form here. Any areas to improve on? Any areas that I am doing well on?

first time doing environment study

hello! i wanted to try guessing the values of the reference image i had to create an environment. i honestly like how everything has decent contrast, but i have no idea what im doing in regards to using color, texturing, and how to achieve higher detail. i felt like for most of this i was scribbling stuff in, but if i wanted to do more detail i would probably hyperfocus on things like individual leaves/twigs which could lose the plot how would you move towards coloring/rendering this? what are things that you observe when painting environments? also, please reccomend resources for studying like videos/reference sites/exercises you do!

Trying to draw my late oc

Is there a way I can improve this before I can really try and color this? It’s been a long while since I got back to drawing :’)

What to improve

Why not inside?

Hi! For this exercise, I assumed that the area inside the headlights was also a shaped shadow. Why isn't that the case? Thanks

This is my friends artwork who wanted feedback and I didn’t rlly know what category to put it in but she was struggling with the arms hand and feet . For reference they’re holding the umbrella by its hook at the bottom of the stick and the umbrella is leaning on the head.
