I made the robe out of the one-piece dress, making the skirt longer and straighter, and the sleeves looser. And of course, I deleted all the unnecessary parts, recoloured the dress and drew a pattern on it. Shoes and trousers don't need much explaining I assume.
The hair I drew on; mostly mirrored and frankly a mess but for a first attempt relatively okay?
The eyes were easy; just went to the template and drew over the original design with red, making the brush's opacity low so I could simply wipe the brush over the eyes without having to avoid the pupils that much.
NOTE: Okay, because it's making me kinda uncomfortable, please, if you have downloaded her model, make her more original. As she is my first ever creation I am rather protective of what happens to her design...
