Apply some blush on the cheeks & make them pop out more. Also adapt some eyeshadow/eyeliner on the upper eye & try making your lashes look very long by curling them so that brings more attention. You can also try putting a cute little nose ring & put some sun glasses on too, that helps.
hmm.. maybe use more blush to make your cheeks pop more. and also maybe make your eyes more dramatic so the attention goes towards your cheeks and eyes more than your nose
To make a nose appear thinner, apply a little bronzer on the sides of it.
