Hi, this looks pretty cool!
Couple of observations about the UI:
- the numbers are a bit small and the font is making them hard to read. In this kind of game I'm probably going to be looking at a lot of stats, so maybe making them larger and easier to read would be a good idea :)
- you have a lot of empty space around portraits and different sections of the UI. The graphics for characters and items look pretty nice, so why not blow them up a bit and reduce some of that empty space?
You have nice pixel art, make it larger!
