Hi, thanks a lot for this lesson, it was interesting to try to do some value studies
As you gonna see in the next picture, i was not brave enought to finish the full range value thought, i'm still a really slow bug, so, since i took like 30 to 45 min for each of the 3 values studie, i already quitte take much more that the time you tell us to take on the full range value
so i only made the integrity of the moutain, wich is was brougt me to draw this specific image, and i just did a rough sketch of one on the cow in the front

have a great day :)
