Main problem for this image was the scarf model, mainly with Sunset Shimmer. The scarf model by default acts like it does on Sci-Twi, where it just covers the neck. On Sunset in the original picture, it covers her neck and her mouth, plus the raw render made it look like a blank blob of orange covering her face instead of a scarf.
