You can't call yourself a '34 artist and not have at least one Tifa pic in your portfolio. It's like the old cartoonist rule that everyone has to draw Mickey Mouse at some point in their career.
I think I've mentioned it before but it's always worth reiterating that Tifa Lockhart is probably the queen of Rule34. You could make a pretty damn good argument that she had a significant impact on the creation of the whole internet cartoon/game porn culture... and she's still going strong. Sure, Sailor Moon and Evangelion had huge followings at the time too but as time has shown they were merely pretenders to the throne.
All hail the queen, baby.
