The shading and rendering are already great! If you want to add more depth to it! •You might want to tone the shining glitters down when you're adding a shadow! • Always find the light source first before rendering! So you won't struggle when you're almost finished with the work I added a multiply layer over the character and erase it, my method so I would know where the light and shadows go but it just creates dramatic effect of that's what you like! Hope this helps!
