Looks fine. The thin red lines on top feel a bit out of place though. If you can pack it up I'll throw on the hands and export it.

I will make some drawings tomorrow. Gotta sleep now.

What gavlig said. Add more loops for a smoother deformation. Dual quaternion skinning will also help keep volume at joints, but I don't know if blender supports it in the viewport.

I get those same artifacts. You won't notice them ingame since they're so small and the basilisk won't be so close to the camera.

Move the supports outwards more. The whole construction feels flimsy when they are so close to the body. Go do some image searchs on industrial machines/vehicles to get a better idea on how they work/look like. Right now the supports are looking too weak compared to the big/topheavy body.

Ditch one rocket pod and turn it into ammo storage/reload mechanism.
