My drawing of Chloe Bennet i did last year. Took around 3 to 4 hours with 2B, 4B and 8B pencils. Added a vignette effect just for fun, still learning how to draw proportionally accurate portraits. Appreciate any constructive criticism! :)
This is only one of the few drawings that i felt have improved my observational skills, mainly because i started to grab the pencil near its end to shade rather than the middle, i found that it helped alot and reduced visible lines in her face.
