I like the designs, they just feel a little... busy. Sometimes having a design that catches your eye can be counterproductive, especially in mecha.
My only objection for the Huckie-Thirty is the visor. By God almighty it looks so crowded in the head... they could've remedied it some by moving the XXX design to the torso, or even split it further so one X is in the middle chest and the rest on the pauldrons. Neup, put them all in the narrow strip that is the face. Augh.
