A part of a Heroes Con 2012 pre-con commission, this Phoenix is Copic markers, white ink, and colored pencil on a sketch cover X-Men #1.
These covers can be really hit or miss in regards to how well they take Copic markers, and even ink. I think it has something to do with the sheen or gloss on the board. And it varies from run to run. In fact, I know artists who flat-out won't do sketch covers as a result. This X-Men #1 blank was honestly great though. Best of the sketch cover stock I've used. I think I was really able to work well with it, having a minimal of problems.
