That's comical is a funny comic, even though the art lacks detail and can look quite childish at times. Everything that is important within the strips is easily recognisable. The way each important object is drawn in a different color is in my opinion a good way to make it stand out among other similarly drawn comics.
The way the art is made has been quite consistent since the start of the comic and has always looked like something created while being bored during classes. Even the lined paper that is usually used at school is still being used for some of the comics. This comic isn't drawn poorly but it looks lke Erad hasn't put too many thought in the way it looks, drawing it digitally, or just using little more time to clean it up could benefit the comic greatly.
The hand drawn text is easily readable by the way.
Even though the art could be better I am a huge fan of the constant stream of jokes, of which many hit their mark. The best thing about the jokes isn't the punchline but to me it usually is the setting in which it was placed. Examples of unexpected locations and unexpected characters are these:
Food Fight
Did I lock the door?
You're not invited
The penis jokes that return every now and then are funny, and even though most of them are rather standard they still make me chuckle. I recommend thinking outside the box a bit more.
Bigger themes like racism and religion are made fun of regularly, something I can only encourage. It might be wise to concider what it is exactly that you are making fun of, some more narrow minded people could be offended and you might scare people away. That's just my opinion though.
In short, I believe some more attention should be put into the art, even though the jokes carry the comic pretty far it could be visually more attactive, comics are, after all, a visual medium.
