Wow, this looks absolutely amazing!
Everything thus far, is simply stunning. I am also loving the plot, quite a turn on the old Pokémon games here. <3
The only thing, so far, that's bothering me is the title screen. I'm sure it can be much better! It's quite an eye-catch, I'll give you that. However, the "aura" just spans up and down, in a loop. I'm sure with a little extra effort, you can make it look wonderful! Now, regarding the Imperial Sky image, I would say the gradient would be better suited if it were vertical, instead of horizontal... but, that's just me. The background is amazingly simple, yet effective.
