Actually your results are not bad considering the machine you are using. What might help you with the ‘flow’ of the fabric is to lighten the presser foot pressure. If your machine has the option to do that, or to raise the height of the foot, it could handle the thickness and intersections better.
If it doesn’t have either of those adjustments and you plan to quilt more now, it may be time to look for a machine that was made for quilting.
