Few to many effects going on, its looking a bit messy.
You more or less lost the render in amongst those C4D renders.
Try not to use that forced lighting (white brush in the top corner), try to look at the render and light according to where it is lit.
Colouration could be better too, if you're using an anime type render its usually best to go for quite bold colours, rather than the washed out ones you've used here.
Hope this helps.
