SK Zippo[potential]

howdy!
i had the idea here since zippo now has the ability to allow you to customize zippos with images and text or engraveings which is awesome[ and not super expensive either]
to make a custom Spiral knights zippo
i had the idea now i cant draw with crap.. i can 3d a bit but i really liked the image they did for the roarmulas twins preview the one of the gremlin standing tall over the super gun puppes and the lone mender on top of the higher one
now then i cropped out a section of the gremlin there with the warhammer and did some gimpshopping to make it spiffy ended up with this pretty much as a preview

what do you think?
it hasent been processed or anything yet so nothings been made or ordered it was a preview
i do wonder with all the copyright stuff going around lately if it would be wise to contact OOO to see if i can use said image this way to begin with XD
anyways thoughs and such ?

yea it would just be for me i dont sell or give away a zippo being a fire bug zippos are something i try to keep in good condition and on my person XD
even for a non smoker i treat my lighter aswell as a smoker or maybe better than some.. XD
If you're just carrying the Zippo around in your pocket rather than making three dozen and trying to sell them, I'm sure it'll be fine.
