During research for a project I came across a book by Benji Davies published in 2011. The book is illustrated this way:
This style may have its merits, though I don't particularly like it, but the interesting thing is that Benji Davies, who is one of my favorites illustrators and a big reference (and also very successful), now works in a completely different way. Here are examples from two of his most recent books, from 2015 and 2016.
I find this evolution very remarkable and a big encouragement. Davies was doing books just a few years ago that were nowhere as distinguishable and sophisticated as the more recent ones.
A clear sign that style keeps changing and one should just concentrate on the work at hand at every single time point - just what I needed right now....
