Use the link with the .png or .gif at the end and put it between [img ] and [/img ] (without the spaces) and post it at original size. If you click any image in the forum it will zoom in
I like this kind of stuff, and it looks ok, but they could be a lot more interesting.
I would change the timing of the movements and make movements faster or slower, maybe adding some ease-in or ease-out too.
The sprites themselves look kind of plain because of the colors. There isn't a lot of contrast and grey isn't the most interesting color
