Wow. Pretty much everything The Avatar said is something I was just about to make a post about myself. Let me just add my two cents.
I love pretty much everything in the game, and that includes the gorgeous and inspired art. But I find that the beautiful kingdom screen, along with the progress of upgrading the different areas of it, get lost behind all these buttons for selecting the guilds, items, etc. And when you DO get an upgrade to the (for instance) elf section of town, you have no way of knowing when it happened, or admiring the change. Maybe have it do some cool transition where it dissolves from the old one to the new one.
Then, repeating what has been mentioned by several before, the dungeon select map feels lacking without details. And since the entire rest of the game is filled with details, this sticks out even more. The sketched look is great, and reminiscent of the setting of the game, but there can be more details in a sketched map.
And as The Avatar mentioned, I don't mean to sound demanding, these really are minor things (polish, really). But they would just add that much more to atmosphere of the final game.
Keep up the good work!
