Make sure you have the correct presser foot. With my old kenmore machine, I simply had to use a 1/4" presser foot. However, with my new Viking, I need the 'piecing foot', not the 1/4" presser foot.
There's nothing wrong with your quilt. It may not be perfect, but what quilt is? Have you learned something? I'm sure you've learned a lot. You will continue to learn too, for many years. Did you enjoy making it? Cutting, sewing, piecing it? Good for you! Congratulations on completing your first quilt top. You're not done yet. You still have the pleasure of quilting and binding it. Good luck and welcome to the wonderful world of quilting!
