Its complete! Even tho I have rush some details at the body part, I did not expect it take so much longer time to render the color, because i am still experimenting all kind of lighting and at the end use photoshop to adjust the facial expression (looks too wired when color)
Definitely not a best way to complete an artwork because it take too much of time, in future i will have to find a quicker and accurate painting way.
The result still seems satisfied me, I was planning to make more rought but i still couldn't find the best brush to do so, my next study will work on brush texture experiment.
