Sofia is from the "Battle arena Toshinden"-series on the original Playstation (Also spinoff-games on Gameboy, Sega Saturn and recently Wii), it was very popular in the early PSX-period, then the "Dead or alive", "Tekken" and "Soul blade" series outclassed "Toshinden" and it faded into obscurity, taking the characters with it (Some pretty cool designs, not just for Sofia)
Oh man.... She looks stunningly pretty here!! Love how gravity's at work here in many many good ways. The shine on that latexy dress is just gorgeous in many, many ways as it's falling and those wrist and ankle cuffs are fantastically detailed.
She looks inviting in every way from her pose to her smile, the couch is a nice compliment and the lighting is really well focused around her. Some lovely color choices all around!
