@Scote Thank you for the feedback! Yes I’ve been confused about how to approach the variety of lens distortion in references, and consolidating it with the perspective in ZBrush.
My general understanding is that most portraiture (including celebrity photo shoots) is done in 35 mm, so I set the angle of view in ZBrush to 35, instead of the default 50. Is it more common to sculpt without perspective at all? I would imagine this to be difficult unless you have reference images taken specifically for your sculpt.
Either way, here are the renders you requested, along some of my references. I appreciate people’s help in the matter!
Also, some more progress. I added some coloring to make it more interesting. The fibermesh on the beard is a bit pathetic, so I’ll rework that a bit tomorrow. I need to add some stitches to the tank top and pants, and then pose it. I did a quick pose earlier today but the model’s leg got really badly messed up, so I’ll have to refresh my memory of ZSphere rigging.
