Nice Use Of The Octan Parts, I Like The Gatling Gun, Though I Must Admit I Feel That The Effect You Used For It Is Inaccurate, It's Too Big, It Looks Like A Shot From A Beam Cannon.... But The Mech Is Awesome.
I agree that the effect for the Gatling gun looks off. Only a single barrel fires at a time, and the flame usually dissipates after a few feet. Yours looks like it's shooting a bunch of fire balls out of the center.
Otherwise, it's awesome. The articulation is impressive and the color scheme is outstanding.
2 things i love about this: 1) the shooting effect on the larger gun. 2) how the mech is owned by an industrial company, you never see company owned mechs, sure you see trucks and space freighters sporting the company colours and logo, but never a mech! it's a neat idea. 5/5!
