I am not sure what you find "wrong" with it. Sometimes when we make things, the final product is less appealing--but I can't see what's wrong with it. It is a simple pattern and actually turned out quite pretty to me. I don't necessarily want it in my bedroom, but many would.
If this is the first quilt that has turned out "wrong" (as in this type of wrong), you can hope that all the rest of your "flops" may turn out so badly! (grin)
I don't see the yellow as light on my main monitor.
When I made the Warm Wishes pattern, I used all of the squares the same size. I see that you made some large squares and then some bordered squares. This ends up making it look like a somewhat different pattern. I see "I"'s and lots of red. If you had used all large squares instead of the bordered squares for some, it would look more like the Warm Wishes as I understand the pattern.
