​I build this bbq, do you think that it is marketable?

So a while ago, I build this bbq. I think it looks great, and was thinking about it as an business opportunity lately. It was quite time intensive, but I think If i maybe would make a smaller version (e.g. only middle tank), It could be sellable. So Do you think it could become a valuable business? And any suggestions how I could stand out to the competition?
