Morning warm-up sketch cards

I sketched out Marvels dynamic duo of Luke Cage and Iron Fist this morning for some practice. I started with the pencil sketch, then inked both and then colored them with tombow markers and finished them off with milky pens. I learned from this and next time, I'lI use colored inks and do initial line art in ink, then color everything and then ink all the details at the end to get richer blacks and no loss of detail. Hope you enjoy these!
