Maybe experiment around with adding some extra shapes to the outer part of the lower sweater to show that as the creases cascade down ( or up depending on how you judge it ) the clothing will have been pushed out and bunched up a bit.
Depending on your style you could also maybe change some of the colours to pop a bit more, more colours of a darker or lighter saturation and hue can be used to emphasise various parts more than others.
