Looks good - it will take lots of practice but you are clearly off to a good start! Enjoy your new baby!
One thing you can do, is purchase a couple of yards of coordinating fabric - one busy / one plain. Load the busy fabric on the bottom/back then load the plain on top with batting, You can practice an entire piece of one stitch and when you take it off you will have something usable for pincushions, bags or some other small project. You can easily see the stitches on the plain fabric and the busy fabric will hide any not "perfect" designs that you might see on the plain side. I did several of these when learning - and occasionally I still do it when I want to try a new longarm pattern.
