There are some miniatures that push the envelope for appearance which almost manage to look cool, and some that just don't. Take the Huron Warrior, for instance. I've seen artwork and mods of the original mini that (with a few minor changes from the original design) manage to pull off a look which might, initially at least, look a bit comical.
Aesthetically, the Phantom is a pretty weird looking miniature which does not, and never ever could, look impressive. It could be the even uglier cousin to the Bowman 'Mech--a BattleMech which looks like a public urinal grew arms and legs and went for a walk.
Functionally, I would not want to meet one on even terms.
