Your quilts will definitely get better. My first quilt was made with four big applique blocks and a lot of smaller five-inch patches, just scraps. I sewed the five-inch patches in rows, and looking at it, you can see some of the seam intersections are off by as much as half an inch.
I was three or four quilts in before I learned that I needed to press the seams of rows in alternating directions so that the corners would match up nicely.
I don't claim to be a perfect quilter now, but if I look at my quilts and compare them, in each one I've learned more and gotten better. You have (and will) too, I'm sure.
