Welcome to the Quilting Board!
We are here to learn how to live in heaven - I'm still learning.
You know, I had to really look for the errors. If they don't jump out at me, I'd say quilt 'er up and count it as practice. Once it's quilted, they won't be obvious at all. I think it's very nice. I haven't been quilting long, and some of my first attempts were disasters. But practice really does make.. well, at least better.

If it's true we learn from our mistakes, I'm going to be a genius!
I have been quilting for 30 years - still not perfect....lol...but, the girls are right. You must double check your cutting - must use a rotary cutter and be sure to line up your ruler markings the same way each time you cut (are you inside the heavy black lines or on the outside edge of them). But the number one thing I have found is in pressing! I use a cut & press board with ruler markings on it - and I actually block the quilt squares as I press with steam. Triangles especially will stretch...so blocking them to the correct size works wonders! Then, just keep doing your piecing...it really does improve with practice! Yours looks fine to me!
I wish mine were more accurate also but as my eyesight goes, I am more careful and still have to overlook the small mistakes.
I love making triangles with Thangles or other printed papers. Also, I never sew the bias triangles together. Put two blocks together, draw diagonal line corner to corner, draw 1/4" from that and sew. Then cut to make two half square triangle blocks. But your applique boggles my mind. I can't imagine the work that went into those wedding rings or the Twelve Days of Christmas. Wow. You are way too hard on yourself. Enjoy what you do well and practice what needs improvement. It's what we all do.

I have similar issues with triangles...I solve that by sticking to squares and rectangles! LOL
As my old teacher always said - practice makes perfect. It is not that bad, keep trying! You should have seen my first quilt. Oh boy, but my quilting friend made me pull out the stitches and do it again! It worked, but I still have mishaps. Don't get dissapointed, keep trying and you will see, in no time everything just works out.
