That is dope, love the color choices AND I LOVE the "ghost" esc red paint on it, you should have that going through the entire set if you plan on finishing it.
Only issue i have with the head is that gray space on the top of it that feels a little plain, woulda loved something cool on it, but the theme looks like a clean robot with minor detail and more focus on the whole "mech" feel.
Good stuff leo
