Just skimmed their history. They have decent art skill, but the jokes often read as being deep for a teenager.

For a hot moment I thought maybe they know English as a second language and the humor was lost in translation. Manga sometimes hits me like that.

That said, there is a reason some artists team up with one making the jokes and the other making the art.

It takes a lot to put your stuff out there, and their panels eventually do have a positive response. I am guessing they are figuring it out.
