Ok this is probably wrong, but in a Dr. Who episode called 'Robots of Death', (one of the best episodes from that series) there was a miner that looked similar to that. It floated on top of sand as it were, and filtered ore out of the debre that entered its forward scoops. This ship appears to have 3 scoops forward and the bridge was sort of like that
In any case, great job on it.
