I like your style.
I started off a bit like you. My first movie, well, it wasn't blammed but it got a low grade. Everyone said "GRAPHICS SUCK! PLOTLINE TOO CONFUSING FOR MY NON-EXISTANT BRAIN"! Grrrr. But then, I got better and my third movie got to the front page! So keep your chin up. Make something that will really amaze people. See, your style, you've got it down. But since it's original, most people can't accept it, they see it as too simple.
I would suggest you change your style to something less...well...passive. The blood-thirsty people of Newgrounds like action, funny, and, uh, other stuff. See, to get noticed you can either go all out on the graphics or on the funny. This is all my opinion so you don't have to follow it. I gave you a 10 for inspiration, I can see great things in you... don't give up. It's good to expirement though.
