Self Portrait

Green Raptor Studios is an online publishing studio started in 2015 by multi-media artist (and all around dinosaur lover) Peter Ahola.  He started drawing at an early age and not stopped since.  Throughout his youth, Peter was always interested in comics and cartoons, which led him to making his own comics and animation from middle school throughout college.  After graduating from George Mason University with BA in art and Visual Technology, Peter officially started publishing under the name Green Raptor Studios with the debut of the webcomic Kalwa, of which he currently writes with his long time high school friend Ryan Greene.  Outside of Kalwa, Peter has created other original characters of which he often tells stories about through his work.  Currently he is continuing his work on Kalwa while also working on one shots for his other characters.
