nice animating skill
But really, Newgrounds isn't meant to be a place to post incomplete works--although I still see it done. The TOS says no works-in-progress--if I remember correctly.
Actually, you should look up the "Kanook" animation. It's recent to Newgrounds. Over half of it is still in pencil test like yours, but it's pretty long and has great animation--has a Disney feel to the artwork. The beginning has color and looks very professional. I suggest it because the author wants to put together a collab, and your style looks like a perfect fit--if you want.
Your animation is very good, but your guy needs to lift with his back or he'll pull a muscle. High marks this time, but I look around Newgrounds for finished works.
