Amateurish, but pretty good. All you need to do is refine your style (pay attention to spelling & grammar, know when to end a joke, stop relying on stock-art sight gags). Still, I laughed at more than one.
Fairly decent stuff man. Not the best, but it's definately not the worst. I agree with not_Scyess with the fact that you should try to always keep punctuation marks in your sentences. Sometimes it can distract from your comics a bit if you choose to leave them out.
