I stumbled upon some Ironsword concept art yesterday when randomly browsing the internet, I thought some of you might find this interesting like I do.

There's other cool stuff on their site as well.

Great animation of the eagle.

The eagle is 9 sprites wide in two frames, but the leftmost and rightmost tile are vertically offset just enough to avoid the 8 sprites per scanline limit. That's genius.
