It all looks very similar like it had a texture bucket dtopped on it when various accent textures unique to different parts of the body could have created a better flow around the body.
you’re not far off the mark here. i must admit , for this one all i was interested in was learning how the detail tools in Z work, so I didn’t put any thought what so ever into the things you mention, I actually just used the same detailing tools all over the mesh (to some degree or other). ahem. now i’m feeling a little ashamed blushing
so!
i’ll put more work into the correlation between texture, details and logical distribution of details in the next study. I’m glad you pointed it out mate, it’s a constructive thing I can work on, so thanks!! 
all the best
