Not NG material. It's good to see that you've started animating but this is, at best, an unfinished experiment. I don't like the term "doodle" but that seems to be what this is. Please keep trying and work towards a more complete project.
Reviews for "Punch"
Sorry, but not sufficent to be stored on Newgrounds for all eternity.
You need cleaner graphic, nicer animation, sound, plot and well everything.
I get that you want to practice with something easy, but this is a site for admirration, not storage, after all.
Why am I watching this? Sorry, but I don't see any ways to improve it, except deleting.
Sorry, man...not much effort or at least craftmanship IMO...I'd spend more time on your work, add music and sfx, make it longer, etc...
that's it? That's all you got?
