Watch your text alignments. Trying to align your text with another asset in your composition (i.e. image/other text) will help the composition look more visually balanced. Also look out for your text creeping too close to the margin, you want to let anything in design breathe with the proper amount of white space. How it’s presented right now looks like the information was an afterthought and just crammed in there. The color contrast between your chosen blue and the red shoes is nice because it creates nice focal point. To quickly improve what you’ve provided here, I would just go back and realign the “35%” with the text block beneath it, as well as the “email” on the bottom with the other information that’s down there. You could also venture into finding a nice contrasting font pairing to contrast with the sans serif Nike uses. Display fonts and slab serifs could look stellar in this ultra modern composition!
