@bit_aspect I mentioned this briefly in my earlier critique, but for gentle slopes, you need more AA than just one pixel to create a smooth appearance. Mugen's sword in particular looks as if you didn't AA it because there's just not enough to hide the "straircase" look.

I made an animation of a couple of edits to show you what I mean. The first just extends the AA so it's more than a pixel. The second uses two AA colours for an even smoother look.
