I love how you did a banded dither in the background. The lighting is great, the anatomy without any jarring things that stick into my eyes like swords ( does that make sense? Lol )
I can clearly see the bond those two have and it fills my heart with joy. Looking forward to that Visual novel! 
It's so beautiful!
The only thing that bothers me, if you don't mind - this one large lightspot on her cheek. I think it is not correct and ruins the jaw form. It should be not as big and be placed on the very edge of the jaw, to my mind, as I can see it on the shoulder and the back of the head.
aw, thank you that is so sweet :3
