I can only say that asking for foundation advice based on pictures is pretty tricky.
You can only look for what suits you and of course it all comes to what kind of skin you have, the state it´s in...basically whatever you are looking for will depend on your skin, and not on Ashley´s.
She´s 18 and has nice skin, so she maybe not even wearing foundation but some tinted moisturizer and concealer, or even just concealer.
As for blush, she is wearing some peach blush that seems to have a bit of glow, you could look for something similar from Bourjois.
But them again, it may not suit you...
