Your quilt is great! I love all of the colors you used. This was a great choice for your first quilt -- no triangles and not too much seam matching -- good for you.
Here's some advice from a fellow quilter: Make a very simple quilting plan. You can always add complexity later. But if you start off doing complex quilting on one square, you have to do it on all of them! Ask me how long it took me to figure that out!
Good luck!
