My first attempt at a character design. All done in Photoshop, using default brushes and some customized texture brushes for surfaces.
He is a futuristic security guard, intent on keeping out intruders. He shoots to kill and takes no prisoners. A humanoid with limited intelligence - the organization keeps tabs on all it's security, making sure they never question their authority or gain outside interests or hobbies. Brain implants are used to prevent curiosity or creative interests developing. No organization wants their staff to be anything more than what is necessary, after all.
To create a similar image would take 2 days (including revisions). The cost would be £200 ($320).
