The type of fliers I would like to try to do... 60's S.F. style psychedelic style fliers. In reality, those porters were strongly rooted in the art nouveau style, which escapes me skills so far. I think I would need finally give in a get used to using paths to be able to do that style of art, instead of my usual free hand stuff.
Now to hunt for some tutorials on how to emulate the style, so I can hopefully avoid some of the trial-and-error process.
