Heh.. Not bad..
I agree with DarkKilauea on the posing & humour, and yea - the size is a tad too big. Keep the size of any comic below 500kb.
I'd also give a 3/5 for the bubbles and sfx.
The outline of the bubbles was a bit too thick, imo, and the text was a tad too small.
Still - a very nice-loking comic.
