Fall, rain, alley by Leonid Afremov

i loved the light effect, but ur painting are repetitive, colors are refreshing which r seen in all ur work,color communicate very well. but the water reflection is quite different in this painting as compared to ur other works...i love ur work... how much time did u took to make this piece, and please tell me how much time will it take to dry? i tried a to work with knife, but at some points i had to make few brush strokes is it all right to use it in a knife paintings, i used acrylic medium for that piece.
