Could somebody point me to a resource/course/book that I can use to learn how to draw/paint fabric? Thanks!

I haven't yet done the lesson on the mouth, ears or hair, but I wanted the experience of taking an art piece from start to finish. Luckily I found this reference where the subject is behind a window. I was hoping for some general feedback and points of improvement. I am aware that the eyes are different sizes. This frustrates me and I need help on how to avoid this. I felt like I spent a long time measuring and working through the lay in (and checking it) but I still did not notice until it was too late. Any help on that or anything else would be appreciated.

hi there as you can see I start in strong blocking out the shapes fair enough and I am actually happy with it but as I continues past it I seem to forget an stage or rush it I don't really know what that results in ruining my practice and i don't seem to get it even with practicing over and over again what do you suggest ? tnx for your feedbacks 🙏

URGENT CRITIQUE - Can someone verify if this makes sense? I am not using a reference, and I know I am a bit blind to errors - subtle and obvious. This is a commission, so if someone can help as soon as possible that would be great. (( Also, this is supposed to be Kid Cudi, if you can also help with capturing the likeness that would be much appreciated )) ((( ***psssstttt @Stan Prokopenko )))
