Aww man I’m really enjoying this! Love the composition and the detail you put into it too. Top notch stuff, reminds me of Red Dead Redemption 2!
Perhaps the only thing I would try differently is to go for slightly more dramatic lighting and removing/reworking the cloud and the mountain. I see the mountain as a sort of the crown jewel of this work, and quite literally the center piece, so it should be the strongest, most detailed and epic part of your scene, while here it is not very defined and hidden by a huge cloud… Think these changes would really elevate the quality of the artwork.
Here is the “Behind the Scenes” article for this remarkable artwork!
Do check out this article, written by the artist himself. It describes the step-by-step process of creating the artwork and provides insight into environment designing in Blender.
