I think that is a block that works better when at least three different fabrics are used in the 9-patch - fabric A for the center, fabric B for the outside corners, and fabric C for the middle side squares.
If you would decide to try using different fabric combinations, undoing that is not a major disaster - it's a good "in front of the TV" project.
I like most of the fabrics that you used - except the dark gray one - 4th in second row, 2nd in third row, second in fourth row, and 2nd in 5th row. The reason I'm not fond of that one is because - on my screen - it looks dirty/dingy compared to the other prints.
