I did these for the /vp/ thread on 4chan. I don’t bother with a tripcode because I feel it gives me more freedom to practice using Photoshop.
I like the /vp/ drawthreads over the /a/ one because
-I don’t have to draw people all the time, and I really like proving to myself I can draw more than one subject
-I don’t have to sift through several pages to reach the drawthread (the /a/ threads update almost as fast as /b/)
-I like seeing how quickly I can do it (the above ones took at least an hour each)
I have yet to try the /v/ thread.
I hope you like them.
