With an aim to practice digital painting, I spent time online in finding a challenging subject/ theme to make.
There I found this image.
This smile of an Ape, inspired yet challenged me to give this a definite hit.
So I started on focusing and noticing the import and complex shaded regions.
There I noticed something like, One nostril is smaller than the other, and even the smile is biased and the wrinkles in the upper lip region.
After jotting the important features, I started making the outline for the same.
Later steps are just illustrated best below in a form of Slide Show (Click on the < > below).
I added color on the painting.
And finally here is the comparison between Original and Digital Art.
Later for My further explorations added certain lighting and color overriding the original art.
