All the best!! I hope you get it right. I didn't use any blending tool for this portrait. I kept colouring in a circular motion. You can use white colour pencil for blending.I used to use grid method but now I go for freehand.
Great job good blending techniques especially for ur first time in his medium good work keep it up careful with the left eyebrow there though! The end is a little too low and too thin But amazing work ur great!!! Bravo!
