That's why I prefer to start an illustration before to think to a too accurate concept of what I want. I save time by avoiding too sophisticated ideas impossible to express. In the main, I have vague intention but I let the surprises come.
And IMHO, I think constraint is vector of creativity. Time is constraint, on a short time we can create suprising stuff, we abandon a too cerebral part of the creation. It's always a good exercing to try to produce a random composition on a short period.
Haha, c’est la raison pour laquelle j’ai arrêté de donner mes temps de réalisation sur de l’illus numérique : un jour un prospect avait calculé les tarifs lui-même en fonction des durées que j’avais indiquées sur du speed painting "dans le genre qu'il voulait"...
J'ai eu toutes les peines du monde à lui expliquer que pour une commande ça marchait pas du tout pareil. Et évidemment on n'a pas bossé ensemble...
That‘s a relief!
