Suggestions for College Portfolio

Here I have 5 pieces I'm considering using for my college portfolio. Elias Valle | scorefolio

For most of my colleges, I can only submit 2 or 3 pieces, what are your suggestions on which I should use?

I'm for sure using the string quartet "A Lily" for every college

Hey @veps,

For me I really love your Wind's Lament, as I actually place this piece as the 2nd place piece myself. But if you wanna put "A Lily" for your portfolio, maybe you can put a solo piano piece with your playing instead to show that you are capable of both composing and playing. I have never made any portfolio myself, but I know that my ( ) piece is once chosen as the exemplar by the Hong Kong's Examination Bureau so maybe that counts.
