If I might suggest, try drawing some lines for the look of water before you start your quilting. When you have the design you like, then use some white chalk to mark your lines on your quilt. I find it easier that way. You might try making your lines half the length. When I am not sure how to quilt something, I go look at Google images. The only error I saw was when you stitched thru the grass applique. Don't be so hard on yourself. We all continue to learn from our mistakes.
