The text at the top could be moved to somewhere lower, also, so that it isn't curving over the barrel.

I feel like you could add more details to this. I like the idea, it's very unique, but it just feels like it's lacking something, like it's too flat on the large areas filled with one color. You could add text to the front of the barrel, below the white stripes: 'POINT HAZARD SIGN TOWARDS THREAT', or something like that. The handle could have more detail as well.
