Thanks everyone that your liked the work. inspired
@amit - actually there was nothing special in the process. however I maintained below steps for this one -
step 1: pencil sketch (in that time I figured out what to draw)
step 2: scan
step3: putting solid colors in photoshop keeping the drawing in the bottom layer. sometimes I put the drawing at the top. in that case I convert this layer to "multiply". i used WACOM.
step4: hide the sketch layer and add shadows and lighting.
step 5: apply some "dodge" and "burn" tool
step6: apply noise, level - 2
all done
cheers!
