OMG, you are unbelievable. I don't manage to remake a straight line as accurately as you do the whole painting:))
Don't beat your self up for not being able to post daily. That is a super high standard you've set. Some theories suggest setting unrealistic goals, others promote the opposite to avoid disappointment. Go with what works best for you, we'll be (or try to be) supportive either way and happy for any post you make:)
To the painting... I'd say there are the same problems as with the squished face-edges and contrast. But here, the edges are not a big deal since they seem to be less defined as you move from the focal point-the eeye looks great, the wrinkles around it too, but further away-beard, crown-thing, the edges are being less and less defined. Like i said, it works as a way to make the person see the focal point.
The contrast is something you are holding back too much. Or maybe that's just me being too influenced by blizzard art;) What i mean is, that on the lighter side, you did well, the darks is where you should be bolder and make them even darker (mouth,, mustache, nose, above the eye, under the cheek). It could work with the gradient of edges to establish a focal point even more.
And i think you forgot to finish the nose:) It's 90 percent done, but there is a touch missing making it look flat instead of richly rounded as in the original.
This reply seems as if i am only criticising your piece as if everything is wrong. When in fact it's great and it is a challenge for me to find something that could be improved. You are more than welcome to visit my thread, to understand how big of a challenge that is for me;)
It is a long reply again... I'll work on that too;)
Keep 'em coming:D
