I´m sorry for beeing so absent recently :(
This post is mostly for a topic that I get a lot of questions about.
Making studys with references is something I usually combine with my warm-ups.
I always have a big pile of photos/magazines and randomly choose some to work with ( or specificly for work related themes ). Time spent is around 20-30 min.
I admit though that I´m not doing that every day, there are sometimes weeks where I just paint some abstract nothings. I also can´t say if this is the right way to go, but it definatly works for me to understand the things I want to learn :)
So here is a small selection from the last months.
edit: sargent study, also around 15min. :|
and some classics
