It's not weird or stupid. I think it's a beautiful piece. You're being too hard on yourself. Don't worry about what "you think others will think". Even if someone gives some harsh criticism, take it with a grain of salt. Just having fun doing it!
Try not to be a perfectionist, and post some more of your pieces. I've seen your deviantArt site, and I think you should share some of those pieces here on Newgrounds as well.
