Dead Alphabet and Columbus, two local bands that really blow my mind.
Many people I know look down on using reference material. My argument, who's to say there's such a thing as cheating in art? The digital age gives us near unlimited creative power, so why create limitations in a medium dependant on imagination?
I can't stress enough how important reference was in painting this, and experience of the actual subject. Advice from me to everyone who loves making art: Use what you know, what you love, and the entire process becomes much more rewarding.
