critic on my understanding color project

My monochromatic picture is one of my favorites because I feel it is truly monochromatic and has a good composition, what is problematic about my monochromatic picture is that there is a white thing in the corner that is kind of distracting. The green and magenta picture was the first picture I took and it is what gave me the idea to do a school theme. It is also good coloring and a good example of the complementary colors, green and magenta. My red and cyan photo took me a lot of time to get it in the right position. I like this photo but it is not my favorite one because it is not as creative as other ones. The photo of the book with the yellow highlights and blue writing is my most problematic one. I feel this way about this photo because the blue looks somewhat purple. This is the photo I plan on changing. My saturated and desaturated pictures I feel have good compositions, but are just okay photos. I feel they are a good example of saturation and desaturation though. The first picture in my series is the one with USA written on bricks, I love this photo and is possibly my favorite, except the photo has a light spot in the corner. The photo of the pencils I think has a good composition, but I wish it had been more focused on the lower parts of the pencils and not as much on the ends of the pencils. My photo with the pencil case and folders is a good picture compositionally, but is also not my favorite photo. The picture of the Mac is another one of my favorites because I like the coloring and the composition and the angle. The picture of the papers inside of the folder is a good photo and I like it a lot and I do not feel there is much wrong with it, it is just not the most creative. My biology book picture is my favorite picture because the color is very important in it.  The photo of the binder is a good picture, but I wish it had focused more to what is in front. The backpack picture is a good photo but the focusing is also kind of odd.
