About the hairsets, there's only one missing but I hope Kinetic is working on it. If you want to work on another one feel free to, they will never be too much, but you should take a look at the ones we have before going on in order to keep the same style.
About the player being naked, don't worry, we first want to complete the set then we will add pants, and later in the next version visible equipments. I see you're working on equipments, just keep in mind you're using an older verion of the spriteset, in fact the punching animation is still weird.
The kimono looks kinda nice except for a too evident gradient shading and I'd make it longer (just my personal taste).
The weapons looks amazing, nothing to say on them, except maybe the shuriken which could use a better antialiasing (but maybe it's only because the gif format was used?)
If you enjoyed making equipments for The Mana World and want to continue I'd suggest:
- start using the png format

- get in touch with our artists irc channel ( #tmwart @ irc.freenode.net ) or if unable to, contact me directly on mmsn, aim, icq, jabber or gtalk.
If you need something to work on, I'd suggest you to complete the Santa's hat sprites (the south one is still missing and don't care about diagonal one, they're not anymore needed). Next you could start working on the other hats. This kind of equipments will be included in 0.0.20 for sure.
Regards.
