Sona, for the space in the stairwell I would recommend the following. The collection of small frames might be nice to add some interest to the space. I really love the lagniappe canvases for a more rustic feel (scroll down for the details on those), or with the bright colors of your outfits and the greenery the vivid metal print would be beautiful!
Your $150 print credit can be applied to any of these options.
