You need to make either
1) Less levels of shadows on the left man's pants OR
2) More variable shadows on the left man's pants
Let's call the left guy #1 and those to the right from him #2, #3, etc.
For 1) I advise you make the shadows on #1 like on #2
For 2) I advise you make the shadows on #1 like on #4.
In general: using many levels of shadows and making them all same/parallel (not actually adding any detail by adding more levels of shadows) produces "weirdness" effect, low-quality, and THAT is what Djjaner-guy below me wanted to say.

It looks weird. More trying. ;)

What concrete things look weird? I need more detailed feedback, man
