I am a major Undertale fan with my own AU. Although, I do not do art or comics like the amazing peope I do and don't follow. My strengths are writing, so I use this site to enjoy comics and art I love.
I think the other one I saw with the big red 'pill ball thing' and the reflection of Sans of both skeleton and human did that for me. It was the reason I began to look into it. Also, love all your art as far as I have seen!
Oh! That's the one I've posted on my tapas feed. And thanks again! I have done way more illustrations for Human Candy but they tend to have spoilers, haha. That's why I didn't post them on Tapas. If you're curious, you can check out my tumblr page.
