My two cents here, if it matters.
First of all this site is the best, and I personally believe your skills improve over time. As long as you are patient and not take anything too personally.
I am not sure about anyone else, but I do notice that there are many original and skillfull entries that are overlooked, especially the contests that are
not anonymous.
For the prize contests, it seems that many skillfull and original entries do receive the votes and comments. Maybe all contests should be anonymous. That way the votes will be based on skill and execution and not on who did it.
Just my opinion
