I like the cropped, second version best cause I have some problems with the equipment on his back; don`t know why he needs such big turbines there
it also looks a bit like this dangerous guy has problems to keep the balance and I can`t see how it`s attached to his body
I`m missing this sharp and crisp textures in your second work, but it looks also interesting
The first dude is wicked, that red light eminating from his suit is a nice effect. I agree with guterrez- he looks off balance in the third shot. I like the very first piece of him, the darkness makes it more evil. MmwWWahaahaaa!!!
