Still there is a lot of space for graphics development. Most of the required graphics is independent from code advancement. The problem here is mostly the lack of artists and probably the lack of a proper management of resources. Code is slowly progressing while unfortunately graphics development seems to have reached a stop.
I see. But the basic character sprites aren't final either. There was many changes needed for the characters, such as the sitting positions as well as the postures. So creating armour and pants were out of question for now, until the sprite is finished.
Moreover, communicating via IRC isn't really the best idea because of time zone problems. Perhaps we should organize the wiki or such so that anyone can pick up creating sprites by registering themself after getting their draft approved? Currectly, it seems like the graphics artists have to go through a lot of trouble just to figure out what should be picked up. Of course, I can create any random sprites or tile, but what is the priority of it? And if it will only get used when another tile/sprite is completed, then one should assist another one instead.
Regarding art styles and such, it is not difficult for artists to adapt to other's styles, so it isn't like two people can't work on the same task at once. And it would be nice if there is a calender to make the deadline for each, so that one can expect when a sprite/tile is completed. And if someone missed the deadline, there should be some follow up and maybe asked another to help.
