Process:
The process started with this preliminary sketch
Added detail to the sketch
More shading and darker details
Added highlights
I used the Adobe Photoshop Sketch app with an Apple Pencil on iPad Pro
I based this work on a photo I found in this interview with Boris Karloff's daughter, Sara Karloff: http://crypticrock.com/interview-sara-karloff-reflections-on-boris-karloff/
Correction:
As it turns out, what I thought was a photo is actually the work of Rick Baker. Thanks to Mark Robinson and Dave Robinson for pointing this out. So I am hereby giving credit to Rick Baker for the awesome work that I mistook for a photograph!
Update: This piece was completed a few years ago, but some time later, I found this photo of Boris Karloff as the Frankenstein Monster that Mr. Baker may have used as his reference for his Z-brush artwork. https://classicmoviemonsters.blogspot.com/2018/11/portrait-of-monster.html?m=1
