Now that i've seen all episodes i see 1 problem.
You like to take thing really slowly, that does ofcourse works with this your style of animation but i don't think you will come far on a site like this that has a whole other thought of what is interesting. Ofc some like it, like myself. But i think you have more succes at a different kind of people who watch it.
Still you maybe really have something here. Think newgrounds need more serious artwork and not only cockjokes and fighting animations.
Just add a little more speed, and make some explosions (explosions who doesn't love them?) more visual.
Hope you make more !
Work hard and soon you'll be on the frontpage.
