I think it looks very classy as it is. Congratulations on a job well done!!! The colours are great and the blocks look very well constructed. What a great way to start off your quilting!!!
(As an aside, did you intend to turn one of the four patches around? If each of the patches in each row are meant to be facing in the same direction, you may want to unpick this one and turn it around. Otherwise you could leave it and if anyone mentions it, just tell them it was intentional (LOL)!)
