1) It's horrific. Not bad art-wise, but there will be a plenty of people that want to take down this image ASAP
2) HentaiLoverXX, don't use third party imageboards as a source, it's make almost impossible to identify author. The best option is pixiv, but author's twitter, Nico accout or any official site is ok.
3) Again, learn to tag. I will not touch this mess.
