Newgrounds.com — Everything, By Everyone.

It's a start. I mainly animate 3D stuffs, but the principles of animation are the same. Right now I would say that you piece is a good starting point. The arm raise, finger transformation and point is smooth. I would say that the real lacking point in this animation is interest. Aside from the arm raise there really isn't much in the way of animation.

There is no staging drawn up behind them which makes it look quite bland. I personally don't really understand the humor behind it but I can't hold that against you, that could just be my own ignorance.

Keep going, create mooooore! Keep going for all to see.

So yea, after all that, good job! Hope that didn't come off as harsh, sir.

^Check that book out, I have found it at most Barnes and Nobles and other franchise book stores. I personally use that book and I think it is great. The anatomy reference is broken down now only at a surface level but also at a bone and musculature level as well.

I am not going to repeat what the other person said, but I think this could really help you with your search to become a stronger artist!

What's the site? Sometimes some sites have a maximum size to the file that is being submitted. Trying changing the image size to half or even a quarter and see if it posts. At least then you might be able to figure out whether or not it is just the overall size of your piece.

Also, are you trying to post the art as an avatar or something like that? Those have very specific size requirements.

Hope this helped.
