Since I'm not at the clothing assigment yet, I can only give some tips why it might be wrong and maybe even help you out with some good recommended youtube videos.
Clothing folds can have extreme value changes:
- Deep Folds with heavy black and easy to spot value changes, has more sudden gradients.
- Light Folds are rather "light" on the shading part, they have relaxed gradients and slowly shift from dark to light.
The edges are another thing, having a good understanding on hard and soft edges is fundamental.
Try hanging a shirt on something and create different light setups. Some are easier than others and slowly building up to harder things is a huge help.
Material and thickness matters too:
- A shirt which is very thin has a lot of folds.
- A shirt that is extremely thick has very little folds because the weight keeps the material straight.
YouTube recommendation which is hopefully enough to help you out:
Since clothing folds are basically overlaps, understanding overlaps in general is a huge help.
You can find a bunch of videos on YouTube about that, even looking at real time drawing videos and studying what they are drawing is super helpful.
Hope this helps, good luck man you got this!
