That does look magnificent!
The only thing I would critique is the hydraulic cylinders - the inner rod would never be painted, at least along the part that travels into the cylinder. Those rods would also never be rusted on a machine where the hydraulics are in working condition. The reason for no paint and no rust is that the seals on a hydraulic system have to be rigid and very tight, but the rod has to be able to move, even a layer of paint (and most surface corrosion, the alloys used tend to be very corrosion resistant anyway) will just be peeled off when the cylinder retracts. If the seal isn’t that tight, the cylinder will leak hydraulic fluid (which is under a lot of pressure) and the system won’t keep working (it needs to be a closed loop). I grew up around heavy equipment and no matter how filthy the rest of the machine gets, the rods on the hydraulic cylinders are always pristine when they’re extended.
I wouldn’t change the paint on the Muthaship’s hydraulics unless it’s easy to do, just mentioning it in case you wanted to take it into account on future models.
