The new Allen has a cool looking-down-at-you look. I love it. =D
Looking at Aster, however...
I need the brim of his hat to be pointing to the right, and the more that I look at him it's like he has no neck =x The yellow lines on the sides of his shirt are supposed to be the straps of his bag--can those be more like how they appear on the male FR hero?
Also the pants. Can you make his pants white with blue lines?
The top of his head seems a little weird. I don't know if you would be able to alter that a little bit or not. I will need an intro sprite for him as well.
Allen in this game is like the rival in DP, he's a longtime friend of the hero. Also, to give you a little bit of an idea of how I imagine him--he's somewhat effeminate, and perhaps insecure about his sexuality. This might explain why Allen has a "superpower" Pokemon like Machop; he has to prove he isn't weak!
