Very nice.
I really liked this one. It was original and really didn't have anything I'd consider to cliche.
When I saw the name of the cereal I will be honest...I Thought it would be another Captain Falcon joke where he punches out from the box. But I was impressed that you managed to avoid the temptation of it. (Most people wouldn't have)
For your first flash I will say you did a very good job. The drawings might not have been top notch but that will easily increase with time.
I look forward to seeing what you come up with next bro.
