More time,different media

Nicer job on capturing your lights, shadows, spaces, and relationships with as fewer lines than before, but I'm not getting enough extremer lines of looser action. Would you please love to loosen up your extreme shapes and lines with 1 hour of 1 minute poses in different colored papers that are not only black or white. Also, look into some construction paper with more colors than what you have available.

The reason why you could and should go ahead with these two suggestion is as a result, your creativity in tones and colors will not only blossom and flower in your personal signature style, but also you dynamic spontaneity in your gestures and tensions will become more and more stronger and ambitious in your figure studies. If you're completely and positively curious about thinking creatively, please kindly look into the free copy of Drawing on the Artist Within, by Betty Edwards if you are willing and able to log in and borrow this.

Hope this stuff has been totally and absolutely concrete and useful.

Thank you for your detailed advice. I will try better and read the adviced book. Right now I have to stick on my paper, may be some packages of my dayly goods can provide me with other colorpaper. Have a nice weekend.
