You don't know how to do comics? Your story board is a little too good to say you "Don't know how". I would say, panels 2, 3 and 4 are a little off putting in what order they are supposed to be read in. It is not really a problem considering it is made so clear what is happening but if the scene were harder to convey it might be trickier. The layout of each panel is pretty perfect which makes it hard to believe you don't know what you are doing, even if you were never outright told you have a good idea, I mean you've read comics before surely. If there is ever a situation where you really don't know what your doing or maybe would like some advice, I would be happy to try and help. I'm not sure what help that might be but ask anyway. This is one of the few situations where I might actually know what I am talking about...... Maybe.
Some people shouldn't have an imagination. They just abuse it.
