2 hours of "structure", 5 mins of inking

Nice expression and proportions. I think this one would be even better if you use long, flowing, confident lines and accentuate the lines closest to the viewer.

I like the aggressive and "untidy" style. Expression is credible.

Greatest job on your ultra-realistic delineation of a facial portrait I've seen, Herbert. That's one of the more greatest jobs I've ever seen!

So, my criticism is that most of the line efficiency is, like you said, and you may and might be right, but it's the most off I've ever felt. Would you please clean up and liven up your lines with 6 more hours of 4 second face and expression sketches?? All on a Timer+ app on your iphone or ipad pro or ipod touch??? (21,600/4=5,400 warmup scribbles/13 days=about 415 scribbles a day)

The reason why you could, should and would do this is because it can, shall and will make your line efficiency the least cluttered, sitffest and ambiguous, and the most dynamic, chrystal clearest, energetic, fluid, vital and liveliest. Don't you worry about not getting too much perfection, you'll be the best with most practice. Good luck with your goal and I hope this helped.
