Who is the Artist?

The person doing the Taylor Swift stuff is absolutely amazing! But he needs to be careful, she didn't go off when they made pics of her doing Kermit the Frog and Oscar the Grouch, but when he made some of her doing black guys she went off the rails and made a huge issue out of it! She is back on track and her self-esteem isn't low enough for her to be perceived doing that, she has an image to protect!
