Hi, thank you for installing this skin now here's what you need to do ;) :

-copy ped.ifp which is a special female animation for the player (of course if you wanted)

-with the program img tools, open gta3.img and replace player.dff and player.txd 


Note: The original model really is not mine ,i've found it from a Russian page which you can found more skin for this model right here: http://www.playground.ru/files/gta_vc_maria_latore_player_model_v2-46504/
