Amazing!! You do realism near-flawlessly - I really admire your pencil shading, it shows what time and effort you put into these. They all look magnificent - I have to say the picture of the man winking (Ian somethingorother? eek sorry, don't know most of them) is my absolute favourite. You got the expression just perfectly - winking people are so hard to draw, lol!
Excellent, amazing work! Keep it up!
