When I get to learn the tool, I usually do not diverge very much from the original tutorial in terms of composition and style as I feel it adds extra parameters in the way of learning. The only change I made was using KitBash3D Utopia UE4 assets for the city. There is still some things I would like to fix such as weird trees, fog, lights and some composition tweaks. It has been great to learn from Joe!
I can't wait to push the knowledge forward using more Megascans assets, create auto materials, my own alpha displacement brushes from World Creator or World Machine, other HDRI, Volumetric Clouds and water from 4.26 etc.
