Thanks @Kosmonaut! You're right and i think today i made the same mistake hahaha! I'm gonna try to give more attention to this in the future!
I ended up making some more shapes and made some shading. I've no idea what i'm doing and i feel that i don't have a good understanding of how light works, but it i did my best today!
it's just a small thing so no big deal, also if I may point out something else it looks like you are doing some interactive shading but I'd play with more than three values though so that you can get a sense of where the darkest shadow is and how far away objects have a lighter or darker grey color depending on the light source you use. The darker greys could be used to differentiate value-wise from the shading color of the other form shadows if that makes sense. If it doesn't let me know I'm tired so I hope it makes sense.
I understand @Kosmonaut, i will keep that in mind, thank you very much !
I've been practicing some more of 1 and 2 point perspective in the last days, i have the bad habit of scraping things out when they don't go very good, so i don't have anything about it to show, but i will try to finish them from now on. I think i got better at it, at least i don't get confused with the many lines anymore, for me it counts as a victory! hahaha
I did some more shapes with the subdivisions this time!
These are some nice faces like you said some of them are too wide while others are too narrow. I also think the nose area would pop out further than you have in some of these as well blocking more of the eye area. overall nice heads though.
also for extreme angles if you see yourself drawing those a lot then continue practicing those but if not I would stick to the more tame face angles so that you are really good at those and use ref for the more extreme angles
I've been learning more about drawing faces, i decided to go on to the parts and practice all together later because i really want to start rendering.
Then i tried the parts...
After this atrocity i decided to learn more about shading, so i studied that some more and i think i got slightly better.

The grind goes on!

Thank you for the nice comments!
Today was a slow day and i didn't produce much, but i wanted to share something that made me really happy, i feel that i have overcome a obstacle that has been a struggle for such a long time.
I was feeling demotivated while trying to structure the heads and decided to see how it would change the way i usually draw.
It may look silly, but today was the first time that i ever felt real joy while painting. For such a long time i hated doing it, and because of that, i focused too much on doing just line art, because of that my pieces would never be trully finished, and i would not give everything i have.
The painting is far from being good and the page is a mess because i wasn't planning on posting it or anything, but i want to keep this as a register to myself.
I hope that this is a starting point, and from now on i can trully give my 100%.
