Well, the DEMO says it's missing the .dll file to run the RGSS, so I can't play that, but from your screenshots I can see that you have done a lot of work since the last time I checked it.
Hmm...I don't like the windowskin, Lol, but that's irrelevant.
I do question your Elemental and Status Resistance sections though. Will they support more afflictions than what you have presented in your screenshots, or will they cause a graphics error of some sort?? Would you be interested in having the menu display icons to show those status and elemental attributes instead of text??
Personally, I would increase the font size of the character's display name by a couple points in all of the windows where it appears. Also, I would give the Hero's name a separate font and add a module to make it easily accessible and easily modified. You could add a module for the Font size too if you do it.
Lastly, I would find some way to merge the item, gold, and command windows together in the original menu display.
Other than those few things, I think this system is gorgeous. Great job Ryexander.
