I think the negative space looks great. The only thing I would suggest is sharpening up her face a bit, because it is too blurry.
Her dress color does not work with the colors you picked for this tag, m8. Either make her dress look different, cover it up somehow, or use a nice amount of photofilters and gradient maps to make it work. Also, I say the tag is too long in comparison the height, but that's just me I guess.
damn SHES FINE./ AS HELL nicest eyes ftw. btw sharpen her. 10/10 for the hotness involved. if the actual stock is bigger, PM ME IT PLEASEEEE
