I love the second shot! There is one big problem with it, though. You have added the incense stick to make it look like the cannon is firing, but you have focused on the back of the cannon. I think you should try shooting it again and place the cannon in the same position as the first, with the same light and background of the second.
This is just my opinion, and you should do whatever you think is best.
P.S. Do you by chance shoot Canon?
