I already told you in my note how much I love it, but I just cannot say it enough times
It just looks so perfect, I totally love the idea what you choose to them!! It's really suits to their relationship, that they are so close to each other yet far away as well ♥
I love their expressions so much, Yuna especially looks super cute in your style with this kind smile and everything!!
Her hair is totally pefrect, the way how you draw and colouring the hairs is one of my favourite parts in your style >w< <333
Yui looks so handsome OMG and I totally adore the way how he looks at Yuna!!! And their pose itself it so good, I feel like they have a "body-language" 
It's so interesting that you used so many blue here yet it doesn't look to be "cold" or something. For me it still has a warm and really nice atmosphere  
EVERYTHING IS JUST SO PERFECT!! Really, I love it SO MUCH!!!  
THANK YOU SO MUCH FOR THIS AMAZING COMMISSION!! ;A;
