I finally took a moment and finished this up. I added the girl on the far right and the "mob" looking guy in the middle, back. Those were the last two. I don't love everything about this, but it was a fun experiment to take all these trendy types and put them together as if they were characters within some sort of group. I did a bunch of little Photoshop nick and tucks to get heads smaller, feet bigger/smaller, arms shorter, weight right, etc. Plus, dropped out the blue underdrawing in Photoshop, so all you see is the graphite line. Its a little cleaner, but still, a sketch.
Amazing work sir
I use a blue Col-Erase pencil and just any black graphite pencil.
