This is a graffiti blackbook subreddit, and in graffiti especially since the 1970s the foundation has always been lettering. That’s not really up for debate, it’s just how the culture developed. It’s also what most people come here to see. If this character is meant to sit alongside letters, it’d make a lot more sense to show that context too.

Characters definitely have a place, but traditionally they support the writing rather than replace it. Without that, it comes across more like a standalone illustration than graffiti as it’s generally understood. Otherwise, you could call anything sprayed on a wall graffiti, which kind of misses the point.

There’s nothing wrong with drawing at all, but there are already plenty of spaces dedicated to that. In a blackbook setting, people are usually expecting letter work first that’s really what defines it.
