I finished this model today and it makes a great display piece. It turned out even better than I anticipated. The picture above shows the 18" version I made, but I also included a 36" version in the download to ease the construction for some. Sandy is unusually tall in the game and the scale of the model reflects that. The only difficult part I encountered involved attaching the face to the helmet (you may need some super glue for that). When properly supported by her wings, she even stands on her own.
