Nice :-)
Oh, meant that the Gold could do with a shade wash and a highlight, just to give it more depth. And compared to your blues, the red fabric doesn't look quite as highlighted. it is likely because the red you used to highlight is closer to the base colour than.the blue is to its base colour.
Edit.
You might be able to hit the middle of the red fabric with a shade,it might just bring the base colour down a tad, which is all it take to make the.highlights pop.
:-D that being said they still look good as they are!
