What's your motivation for entering the competition? It looks like you have made a beer that's not particularly in line with any of the BJCP styles. There is absolutely nothing wrong with that, and it sounds delicious, but the judges will be evaluating your beer against the style guidelines, and not for overall enjoyment. It seems it will have too much hop character for a cream ale, but the two pounds of corn will probably bring it out of style for a blonde or pale ale. No matter how objectively delicious it is, it probably won't score all that well. If you just want general feedback on whether it's good or not, you're probably better off taking it to a homebrew club meeting. If you're determined to enter it, I'd say 34B, Mixed-Style Beer (Cream Ale/Pale Ale), but I don't have much experience with what ends up in that category in competitions.
