your drawing is indeed very good, i love the first charcoal picture (i've tried charcoal and i confess that that is impressive). i also love the colors on the mural and the perspective drawing. not a big fan of sand sculptures but it looks cute.
i remember one time you posted in here with proportion sketches/tests. i think these faces you made are very good, but the body still needs some fixes. i wonder that you made its shading all "messed up" since it was charcoal?
keep up the good work, you got some talent flowing
comparing both charcoal paintings, i wonder why you made a quick shading on the second picture if you can make it precise (as we all see in the first picture)
