The animations are done with adobe flash, the concept behind it is very easy. every character is cut up into pieces and then rigged to a bone system, the hard part is making it Not look like card board cut outs. so I make subtle movements and make some custom frames when needed, like when the shield is facing the camera or on his side.
I'm linking a video which shows an example of the bone system at work.

That's pretty cool, must have tooken quite some time to physically draw those sprites especially with those details. I was just wondering where you were able to learn your art skills? I'll be looking into vector art soon, but I really like your style of art, is there a name for it?
And also have you heard of spriter? It features similar functions to adobe flash and also comes with png export, or you can set your spriter image as a scml object in Construct 2, but personally I would rather stick with the png export for now. I think in general spriting,art and animation is something I'll research on soon and watching that video was fairly helpful so thanks for posting <img src="smileys/smiley17.gif" border="0" align="middle">
