Bon allez pour mon 100eme post sur ce forum...je met une nouvelle photo.
Je n'ai pas vraiment su ou la placer.
Donc on va dire que c'est une scène de rue...(non retouché bien sur  Siffle)

Mouais, les retouches sont belles sur certains endroits, baclées sur d'autres (cf le ciel en haut à droite, t'en as pas oublié un peu ? Clind d'oeil)

Il n'empêche ceci dit, l'effet est réussi : belles couleurs, mouvement, angle intéressant...
Un souci sur le site ? Un coup de main à donner ?
Demandez-moi !
