You did excellent, I especially like this rendition of Tifa. You really captured her stout and sturdy stature without over exaggerating traits. The costume concept looks good and genuine to the game, but has your own design flare to it. ...and so importantly, you seemingly really capture a soft feminine beauty, despite maintaining a hard-body tone, without uncharacteristic make-up. She has that natural and almost homely anima, but still gorgeous.
Tifa's chest size has often been silently debated (mostly exaggerated) throughout the franchise by the fans. Personally, I prefer her big-breasted, not because of typical male fan hormones, but because I feel like in some cases, it's a big part of what makes a strong woman look the part, and the fact that you drew her both well-endowed and with the muscles to back up her fisticuff-based fighting style makes her look really fascinating to me. Needless o say, I enjoy this drawing.
