Nice work with the demon head, no critiques, but a little texture would be nice. I don't really like the swords, though.
I see so many sword drawings on NG and they all look the same, detailed doodles of an asymmetrical sword that's supposed to look 'badass', But they just look untidy and silly.
Try drawing someone/something holding a dangerous sword, I don't mean a small guy with a huge anime sword. But take away the little details, add a little something to make it unique, then put it in something.
You can't have a nasty looking sword on it's own. You have to put it in a nasty position, you can make a soup spoon look "nasty" if you draw it being rammed down someones throat.
Go for it :)
