I think your stitches look great! I'm also rather new at this and am finding the more I practice the better it looks.
As for people noticing, I really don't think most people notice stitching, unless you're a fellow quilter and even then I don't think it's a big deal. By the looks of yours I don't think you have anything to worry about.
I keep reminding myself to relax as I tend to get tightened up when FMQ.
You're doing well
