You already got great critique on this one, but I just think there are a few things more to comment on. Mainly, when doing studies, you want to make the value structure having the same amount of contrast as the reference, otherwise the values might get too confusing for your eyes and won't be able to make them accurate or close to accurate. Values are really important but the thing about them is as long as you get the contrast right, you can make the image darker or lighter and it will still work. Lastly I believe that although it's not that important of a thing, bounce light helps a lot to show form, get cool looking hues in there and help to sell the overlaps of similar value forms being overlaped. | Artwod Feedback
