I'd love to see a little more detail in the faces, just to see their expressions so I know what they are thinking - the title suggests they are angry and I can't really tell that from the poses alone... except the rude finger... but looking good so far ^_^
I am not a fan of the middle finger but poses look as if they were lounging and I emailed you what I think... it just needs to be refined....Try to update it this week and edit the same post to show your progress.
I personally think that the finger totally exposes the pirates for what they are... and tells a lot about the story, I am excited to see what new things you come up with...
thank you for the comments. @lesley - the title implies that ninjas and pirates need not fight, they can chill together. the ninja (being the sly, subtle one) enjoys a drink, while the pirate is showed being vulgar and rude (and piraty, like "arrrgh, piss off matey") to the onlooker. i am not great at animation stuff, but will try to refine the faces and clothes.
