And here's a close up shot of Optimus' head, please ignore the skinny neck as it was just a placeholder and this was just a test to make sure Prime's head looked the way I wanted it to when fully coloured.
Thank you for giving Optimus his real face back, he never looks natural with a mouth, and I like seeing bots and cons with a variety of different face designs, from mouths to faceplates or even those awesome cheek lights Wheeljack is famous for, or Shockwave's cyclops mug lol (and to be honest, considering how emotionally dead Optimus is Transformers Prime, ya have to wonder what the point was of giving him a humanoid face and mouth if they weren't gonna let him emote like Optimus Primal or TFA Optimus lol).
Optimus DOES have a mouth under the faceplate in this series, but you will NEVER see it, I can promise the faceplate never comes off him I don't really have a problem with "new" Optimuses having retractable mouthplates, but I felt that for this incarnation, if it retracted then it just didn't feel "nostalgic" enough. I really wanted him to feel at least somewhat like the Optimus from the original G1 cartoon, and having his faceplate stay on 100% of the time made it feel more like that to me, even with a redesigned body. I guess in my head, aside from some exceptions like Shockwave for example, I see guys like Wheeljack as having full faces under those mouthplates or visors or whatnot, but I never plan on showing them, lol. Like Wheeljack just doesn't feel like Wheeljack without his weird mouthplate thingy
He DOES have a face under the faceplate, but he never takes it off. But if you want to see the face, just wait until Ultra Magnus appears, he is Optimus' identical twin (but with a white colour scheme) and his faceplate comes off
My fave is that teeny wrinkle of concern in his brow. Because dangitall, HE CARES! And I like that touch of red in the helm. It's new. And it's kewl. It really works to pop the colors. But I never doubt for a moment that it's Prime.
Its not too far off as it is There's a crap CGI mock up model used for reference as a base to help me out and to appease the OCD what rules my existence (lol). Its like a crappy, simpler version of what I used do wayyyy back when I first started on dA (like the Shockblast and Landmine pics) but I have to do more "me art" work over top of it, its like a robot shaped measuring tape if you will
