transparent background, porfa. you can dl giffy or use iaza.com if your pixelling program doesn't support transparency. the swords are looking nice, but the hilts on both look pretty clunky. the handle should probably be thinner, with a pommel on the end. I also expect a sharper point, namely on the sword on our left.
here's some sword anatomy for ya
Nice job: few colours, a lot of impressions. The shield could use a bit less colours, though.
