Your blocks look great! Trust me, I am new too, and my first quilt top is not the greatest, because I was not always able to line up the points. Yours looks way better than mine. But even though mine is slightly off kilter in certain areas... The one saving grace is that I used pretty fabric. :) It seems to hide the imperfections quite well.
You chose very nice fabric that looks great together. The soft blue would look great for the sashing.
I would never donate my first attempts at quilting. I think no matter what, you will be very pleased with it once you are done. There is something to be said for accomplishing a task that is time consuming and not easy to do on the first try.
