Haha! Everyone seems to be getting on the Homestuck bandwagon. Everyone tends to draw a really good Karkat. I've read only very seldom, (I just can't get passed the beggining), but from what I see it has a pretty epic story. Anyways, great job!
Well, don't really know, because you'll miss a big part of the story. I didn't read some parts too, but even if you don't read it I think you'll be ok and you always can search something about it to not miss what happened ^^
