i think her drawings are adorable, but i do tend to be more fashion-conscious. Hello! Project t-shirts as it is aren't very stylish (in fit/fabric), so i just feel frumpier when i wear them. when they don't even have a stylish design (it's more funny than anything) i feel even less cute. xDD
so i wish she would do either a design without Suu-san, or a more stylish version of the designs she does now.
however, if the fit/fabric was better (like the Rival Survival shirts
or Goto Maki's G-Emotion Final shirts, I WOULD DIE OF HAPPINESS if they started making t-shirts like that) almost any design would work! as long as they pick good colors (which they often don't do.. see the frequency with which they pair Riho's red color with yellow writing), it would look good.
i've considered cutting the collar of the regular shirts so that they're girlier (like the H!P girls themselves sometimes do) but then i'm like SACRILEGE, MUST NOT DEFILE PRECIOUS MERCHANDISE.
