This last clip is perhaps the most evolutionary of all four. It deals with the completion of blending the colours and adding texture. The hair is added in and there are some major positional adjustments too, even at this late stage.
At the beginning of the video you'll see my 'to do list' layer turned on briefly. This is to remind myself what needs work since I haven't touched the piece for a couple of days. It's a quick guide which takes minutes to create. I decided to reposition one of the horns and his left eye and you'll see my very rudimentary brow line pop up briefly.
To quickly add texture to suggest pores in the skin, I've utilised the Spacing & Scatter options in the Brushes palette. This handy feature, combined with a variety of colours can produce great results.
Hopefully by watching all four videos in sequence, you'll see how a piece can evolve at a variety of speeds. Sometimes the changes can be very obvious but sometimes the subtle work can be the most effective.
Patience & perseverence is the key.
