I think your quilt looks great for a first try. The quilts that I have done double sided I did a loopy or meander free motion. I have the brother 1500 and I love it. No tension problems and because you have 4 adjustments for the feed dogs I can SITD with a regular foot. I think the thing about redoing is how much it will bother you. In my opinion SITD is actually more difficult than fmq. And like has already been said, after you wash it, it will look different. Great job!
