I like it. I particularly like the viewing gear at the front, great idea.
I do have two minor 'constructive criticisms' though. The first is the top of the legs don't really seem attached to the body. Even as a sci-fi thing I'd have trouble with the flexible cables supporting it when the lower part is a big fat support leg, it should either use one or the other. For VSF where flexible supporting cables is a bit advanced, even more so. I'd probably add a rod between the leg and body, leaving the cabling as just that.
The second thing is the chimney, it doesn't meet with the hull. There are two ways of dealing with the problem of a flat tube meeting a curved surface. Easiest way is drill a hole and put the tube in that. That's not always possible however. The other way is to make the tube out of plastic and put sand paper over the curved surface. Then rub the tube over the sandpaper until the edges touch it. When the sandpaper is removed the tube should fit snugly against the curve.
As I said, they're minor points on a nice conversion, just something to bear in mind on other works.
