i just sorta skimmed it, but er
I think there's a bit too much white? the numbers and etc. are basically a white outline on the menu atm. the command area (with names and atb and etc.) are sorta similar, and visibility can vary considerably- as a matter of fact, the brick ground the screenshots are on atm make it a lil bit hard to read it.
for the menu selection area, where the mouse/pointer/hand/etc/whatever is, the words seem dimmed out, and as the quantity is right next to it, in white, it makes it seem as if we can't use the item. Whenever the pointer/selection is on the item, I recommend that the text turns light/highlights white in addition to the selection pointer hand thing? Course this has issues with the whole white thing I mentioned previously, but whatnevers.
one more thing, when it's whoever's turn that is supposed to be attacking (flamma in the screenshot above i guess), are they slightly more animated or highlighted out or whatevers? prolly help. Of course the screenshot's not the final or anything, what with the placeholders, just noting.
Not sure if the help text on the screen should be that specific font. I think almost all the other fonts are the same, so yeah...
on a different note, multiple party member abilities woot
edit:
btw hope you get the defense command right. If all it does is half damage or some other similar thing, I'd personally see little reason to use it. Then again, I've not much knowledge of the battle system and related in general.
