I really like the composition in this, but, unfortunately, it depicts a scene from a chapter that takes place in Dipper's bedroom. Being in the bedroom, a love seat simply didn't work.
Plus, since the scene starts with Stargazer talking to Dipper, how does Star end up behind the love seat?
So, I had him redraw it. The result of that can be seen here
Word to the wise, artists: check with the patron before finishing work. Make sure you've done it right. It will save you extra work in the long run.
