From my Illustration 1 final, we had to do concept art from books our teacher gave us. I chose the book Angelology. We had to do 3 characters and 2 environments. I chose the Nephilim survivor of Noah's Flood (call him steve personally cause I don't remember if he had a name or not), Archangel Gabriel's Lyre, and the Archangel. For the two environments: I chose Evangeline's (main character) workspace, and The Cave God threw the fallen angels and caged them.
Of course from these thumbnails we color three characters and one environment to finish off the final.
