It's really cool how you use prismacolors the same way I do when I'm not taking train pics...Maybe I go a little lighter but then when I scan and Photoshop it all comes together! Awesome tutorial and methodology !
You should invest in an electric sharpener. I bought one at Walmart like 6 years back and its yet to break a single tip while sharpening. Best fucking 13 buck investment ever.
I really do enjoy your work in the most oddest of ways. It's almost like a man watching the steady drying of paint, seeing how the gloss disappears with each breath blown over it. Most would wonder why he's watching it, but their just something explainable to keep his eyes locked onto it.
Anyway yet another great tutorial :3
