My only main concern with the vplusblue style is that it contrasts too suddenly on the account/password screen (the very first screen a player would see), it goes from a white background, to an electric blue border, to a dark blue gradient background.
The border for this window also seems too rigid.
I'd really like to see a style that can be associated with Graal in some way, either by a consistent colour theme (shades of green?) or a scroll like window similar (but not necessarily the same) to what we use on Classic:
