I can't imagine someone not being proud to make or own that decoy. That being said, a great decoy may not always make a great 'contest decoy'.
You mention seeing your decoy bob in the water. While the composite keel may be more than adequate for hunting conditions, is it the best for pool conditions? Without adjusting any weight, you are simply relying on the density of the material to be exactly what you need. It may be or may not. Had you added a little weight, it may have improved the performance.
I also notice that on your decoy you don't have the typical height on the delineation of the side and back feathers. It seems most ringneck decoys have this line rise markedly up and in at the rear. Is yours wrong? No. But maybe the judges like it the other way.
From any pictures of the Westlake pool I have seen, the lighting looks poor at best. Perhaps by really brightening up any of the white or lighter areas, a decoy would stand out a bit more in the sub par lighting.
Take these suggestions for what they are worth. I am certainly not a contest decoy carver, maybe barely a carver. Just my observations and what I would do in your shoes. What you should really do is talk to some successful contest carvers. It is good to learn from your mistakes, but better to learn from someone else's.
