For those who aren't keeping up with the Discord's #core_feedback channel, a bunch of discussion occurred with the hopes of improving this sprite, and these are the two options we ended up coming to, with both of these options including different sword angles. The first one tries to focus on mostly blue and cyan while the second one adds in some white for his feet and antennas.

Personally I'm not sure which of these four sprites should be used, but I would say that any of these versions are certainly better than the one that is posted there.
Alright, so it's been almost a month and nobody's really been talking about this. In my opinion I really like the ones Sonic posted, but that's probably me being biased since I helped with it.
There's also been another Swordman sprite made by Molly/Geno, which also looks pretty nice.

Anyways, getting to the point. I think there should be some kind of poll on this. Keep the current skin, Use Korby's, Use the one Sonic posted, or use Molly/Geno's. I'd be fine with pretty much all of these except for using the one that's used in the OP, but it'd be nice to hear other people's opinions on this too.
