Hey man great work. I haven't seen one of these before even though it seems almost obvious after seeing yours. Of all the non-car customs like Insecticons and Seekers this one really works well. The decals are just that little bit of extra icing that puts it over the top.
That's looking sharp man, G1 nostalgia oozes from it. Would be a wicked start for an Alt Devastator. I still want to make an Omega from Cybertron Menasor like you did awhile back.
