Get rid of the Pink above windows and leave black (for Logo / "Strap line ",Route if specific etc...)
Pink triangle below window needs to be different colour that blends better, or use Harlequin style design blending Gold, Beige, Dark Red/brown etc.. - e.g ... like that on Etihad Airways Tail pattern. 

Use of Metallic paint in similar shades would enhance image.  Metallic Blue (Durham Diamond shade)and Metallic Dark Red on Corporate Livery, also  replacing White with Silver and/or Yellow with Gold.

Variations of the colours above on 673 remind me of close resemblance to new East Yorkshire livery, which is good at blending Traditional  with modern corporate design

Thoughts...
