Gosh, that CF tow reinforcement on the nose looks just... so wrong. Especially with those gaps.
At least add some tow in there over / across the seam line (which is the weakest part of this nose).

It's a bit hard to see in your pics, so for others: the MK mounts were typically mounted so that the center beam (between the rubber / plastic 'soft mounts, depending on which model MK Soft mount one has) FLOATS over the main engine support beams. This is what allows the soft mount to function. It has to 'float' freely in order to absorb the vibrations. So the MK units were typically mounted on an aluminum 'standoff' a couple of mm thick. It appears that you have done this correctly.
