I've made several music videos before, but never shown them or entered them in contests or anything; they were really just practice at editing and whatnot. Just recently, I finished what I feel is a masterpiece (for me anyway). My friends love it and have coaxed me to enter the Anime Boston video contest. I got really excited about it and am pledging the next two months to refining and prepping my work.
But I just searched here for people entering the Anime Boston one and someone's using the same song I am. Would it be a good idea to enter anyway? I'm using a completely different Anime than this person is. I know I can enter all sorts of cons all over the place, but I kinda had my heart set on going to my local con with my friends and seeing my work on the screen.
Any advice would be great, thanks!
