This may be too much work so I understand if you don't want to do it, but this person doesn't give us the source. So I was wondering if someone would tell me the artists for the images.

We cannot possibly identify every single image on someone's tumblr, that is way too many to even begin to identify in one go. If you have a couple pieces that you're particularly interested in, feel free to post links on the board. Otherwise, you may need to do some digging yourself. I'd recommend reverse-image searching on Google and using SauceNao.com. I hope you understand.
