As of this writing, I work with a 15 inch screen at 2048 x 1280. What this means is that there’s not enough space to fill the screen with references, and because of that, I have a habit of doing things from memories. I’m a bit lazy to open up references when all I’m doing is experimental sculpting on the fly. For me, one way to counter this is to have an actual figure sitting on my desk. There. No more excuses for not getting the neck right. You simply can’t trust your memories as evidenced in the fact that people still forget where they put their keys (pun intended).
Also, take advantage of that empty wall of yours. Whatever you’re struggling with or needed to be reminded of, print them and stick it.
