This is a Zentradi warrior from the 1982 TV show "Superdimensional Fortress Macross"
Huge, genetically engineered warrior caste bread by the creators of the human race, called the protoculture (I believe). They are completely meant for combat, bred to do just that. The genetical modifications include them being 8 meters tall (27 feet). Their body armor is more than battle tank armor due to the sheer size alone.
The Zentradi caste turned on their creators a long, long time ago and fought long wars with the supervision army, the normal military force of the protoculture.
I'm especially pleased with this one as it didn't take more than about 5 hours. I was going to have it be a speedish paint at first, then I thought "what the hell, make it more detailed and scenic" and was starting to add a background, but commissions interrupted me and I was just going to scrap it. Instead now, I made it more like a Zentradi themed simple poster. Probably the best result I've gotten in such a short time.
This isn't entirely photoshop CS, I also made use of a 3d program called Poser 5. I simply generated a (normally dressed) man character in this pose that I wanted, then painted straight over him. Cheap but effective
Keep in mind that this is the state it was in before, without any polish (just yanked out of WIP), with some poster elements added and posted. Not exactly a polished work. But I think it's good enough not to be in scraps despite all the (hopefully not too apparent) flaws.
Added black border and background Zentradi logo.
