Now this is a refreshing style, very lovely.
Colors are vivid and blend together flawlessly. The doves are a nice touch as well.

Only immediate problems that i can spot, the proportion of the two bent fingers on her left hand is a little off, her thumb there looks slightly strange, and the area right above her breasts looks a little rushed.

I do really like how the artist drew rem's hair, and her eyes fit the style of the overall artwork very nicely.

Viewing this artwork puts a smile on my face. I can tell that bright emotions of happiness and joy were put into the creation of this piece. :)
