quality works

these are the 5 works that I am planning to submit for quality. What color matt would work the best with the multi-media piece of Hailey?

I plan to use this photo for both my concentration and quality sections since this was my scholastic piece...

This is a silhouette of Rhianna that I did while we were working on our group project this past weekend...

Thee Book Tree

This is a photo taken in the Peak to Peak library of an oragami tree. I really enjoy the colors as well as the juxtaposition of the natural with the contrived. I think that it is well composed and without distractions. Would the photo be improved by changing it to black and white/ desaturating the colors more?
