Hey there, leofelco816.
I think you're doing the nicest job on your foot sketch, love the looser and lighter touch on it. Well, if I could suggest you some solid advice, then it would be to please, please, please work out very longer and larger in a notebook paper from notebooks, with a 4b-10b pencil, in 111 minutes of 28 second hands and foot poses???? (111 x 60=6660 seconds, 6660/28 sec poses= about 238 poses)
As a result, there are two reasons:First, it's to help you less and less precious with your drawings, and to get a much wider range of tones. And second, to help make your hands and feet less stiffest, and the most energetic, fluidest, and liveliest. Cheers, and I hope you've found this completely and totally helpful, encouraging, and informative, and gossipy.
