this reminds me of an image I saw on google back in mid school, it was titled "Captain Rex" and it seemed like something out of Star Trek ya know? the one with Patrick Stewart in it and it showed an alien with a green dinosaur head and he was in an astronaut suit too
sorry for rambling but I just had to find something close to that image
thank you very much!, well is not really an already existent character but i just love dinosaurs!, this is part of the concept im doing for a little animated videoclip, it involves dinosaurs, scifi, explosions machinery and epicness! XD, im working on it right now, i hope to upload more of this project soon!
