This is something I drew for my mom (who's been a huge Beatles fan since before I was born) for Christmas last year. I used some fine tip microns and a brush pen to do Lennon and ink wash for his hair and the city skyline.
And I'm still working up colors on the Deadpool thing. I haven't done any coloring in, like, 5 years so I'm rusty. Reeeeeeealy rusty.
