Excellent sketchbook! I am new here and I went through the whole sketchbook to come to the final post, so I've had a creative overload. this sketchbook is a great kaleidoscope of images. I will be coming back for more though.
Great studies!! Some things i picked up while reading Andrew loomis Creative illustrations: Shadow makes the form and color appears most vibrant near the areas of light. When as in shadow - color loses its brilliancy. Also Pure blacks seldom appear in nature. Hope you get something out of those brief annotations, But really great Studies, Keep it up
your still lifes are so cool! Keep pushing those portraits, you're definately getting there! For example, your first and last portraits in the last post have some minor glitches I can't even pinpoint, but your Sargent in #287 and the little girl in #289 are astonishing!!! You definately have it down, it's just a matter of consistency.
life studies are rock solid, nothing much to crit there
For portraits, sometimes they seem a little bit off (at least for me). Maybe try to get the measurements right in the sketch before detailing too much. But can be just me, haven't drawn some asian people in a long time.
What I really like about the portraits is the color palette. Great mood in every one of them.
Keep it up!
