Up close it looks very busy, but from a distance it works quite nicely. Good job on your piecing! It looks great!
And I really like your fabrics too!
If you have enough fabric to do so, the lighter fabric with the larger print could become the focal fabric, perhaps using it in a large square (4 small squares wide) with strips (one square x 2 squares in size) to create the same design, but less cut up and thus possibly more pleasing.
This should not be much (if at all) more difficult than the way you did this one. And the corners could be done in a similar fashion.
But if you decide you like it the way it is, by all means go for it!
If you want more specific cutting directions for what I mean, PM me and I will gladly explain further.
