Here is another challenge, inspired by the 5 artist challenge in another thread somewhere, just reversed.
Each week (as long as there is sufficient interest) I'll post a head-shot of someone's OC that they have personally drawn, and your job is to draw the same headshot, in approximately the same pose and expression, just drawing it using your own unique style. It can be done sketchy, or coloured, or nicely inked or whatever, just so long as people have a go. Please don't include backgrounds, let's keep this to the head-shot only. Everyone should post them in this thread, without spoilers (so everyone can admire them). At the end, if I have time, I'll collect them all up into one image to compare and contrast.
To choose the next head to draw, I put everyone who has previously drawn in this thread into a spreadsheet, with a separate entry for each time you submit. I select a random person from this list (minus those who wish to opt out), and they can submit a head to draw next week. If you aren't interested in having a headshot done in this way (madness!) then just mention that when you post, or flick me a PM.
She's in her mid-20s and is the younger sister of main character, Charlotte. She usually comes off as a bit of a stuck up rich girl, but does have a soft (as well as nerdy) side to her with those she's comfortable with.
