An excellent render. I think I have seen some other works by you, but will have to do some reconnoitering of my back tracks to be certain. This is by no means a critique, as I can not do this kind of art. I like the overall design and arrangement of the tanker. Although, the basic configuration could be used to haul anything. The canisters could be detached and taken into a large shuttle or connected to a station and cargo separated and dispersed to its destination. Though from the blue lights in the bow, I can see this must be quite a large cargo bulk container/carrier. Three-hundred meters plus I should think. This is a good design and shows a high order of technical expertise and imagination. Great Work, hope to see more, and best of luck in your future endeavors.
