- Does he use arabesques?
- Does he use oval or circular compositions?
In general, the internet-famous guys simply don't. They're all about straight lines. Rectilinear shapes, often with a strong diagonal. Whenever they can manage it, they shove in an actual diagonal line, and when they can't, they imply the diagonal by placing stuff in opposite corners. This is all very well and good, but it's a pretty narrow palette of technique.
I use the pronoun "he" deliberately, here, because I cannot offhand name a single woman who does this stupid heavily gridded derivative stuff.
And, for reference, I am rotten at this sort of thing. But then, I am not offering any workshops.
