Hi Guys,
here is my submission for this lesson, it was hard to find the right colors for the chest and the gold, at firs i was going to delete everything thinking it was bad because of the shape, but playing with the colours i found out the “perfect” combination for me.
The second shadow(the top-left light one) was quite a challenge.
I even made the xxs version too to help me while shading the “big” one, ending liking them more then the deteiled chests 
.
Reece, good job on the explanations, clear and effective keep it up! 
Peace, Moffu.
