Crimson M-2 by Jasro8. It looks nice and solid
and it doesn't try to get too fancy. Nicely done.
Explore Strange New Worlds by SweStar. This is a neat
little diorama. The mecha designs are simple and clean.
Mecha Wars: Grievous MK1 by Grantmasters. A blend of
old parts and new techniques to create a Star Wars character.
is meant to be the pilot for a much larger mech but I think
it's interesting in and of itself. It also carries a pilot!
Tau Fire Warrior Team by Garry_Rocks. These are meant to be Warhammer 40K scale, but I think they might be good for MFZ. Note: This is a render using parts colors that don't occur in real life.
