Hey guys,
I’m currently working on a sculpt of Erwin Smith from AoT.
Was wondering if you can give me some advises to make him look more similar to references, I have a feeling that the image just slips away even though I’m getting closer to it!
Reference:
Hello @Sanek94cool
This is only my opinion, and I am not a professional art instructor. You should seek out artistic instruction and resources for personal skill training. 
Well, first you need to determine what sort of look you are trying to accomplish, and select appropriate reference. Are you trying to recreate that highly abstracted cartoon figure in 3 dimensions and have it look like a cartoon, or are you trying to create a realistic looking human figure that resembles the stylized cartoon?
You have shown a picture of a cartoon here, but appear to aiming for a more realistic looking sculpt. To sculpt realistic human anatomy, you need to study anatomy from realistic human reference. A cartoon is only suitable for reference to recreate that cartoon. This may be fine for a more stylized approach, but will not inform you on how to create realistic looking anatomy.
Good luck!
My aim is in between. I do want to keep a realistic proportions, but in the same time to keep cartoonish style. Attack on Titan style is somewhat targeting a realistic anatomy, but exagerated facial proportions, I want to follow this path.
I like the approach of FF7 Remake style, which is also semi-realistic. I should say that’s the one I am trying to approach.
