So, for the tracing part, I got the idea to print out the photos, to put them in sheet protectors and to use permanent markers to trace it.
Thank god I learned that you can "erase" permanent markers by drawing over it with dry erase markers, makes the job much easier.
Once it'll be done, I'll remove the photo from the sheet protector, and then trace over the tracing of the photo I traced over with the protector, lots of trace in this sentence, gonna have to trace the reason back.

the head is always the part to bring a character to life, even if the body language is important. feel free to leave your thoughts.
