Great progress! ![]()
Are you using the full range for the lighting? There's an option to unlock the full range:
You could make this pop even more by using physical lighting values, so you would have a bigger range of values between bright and dark areas (right now the values look a bit clamped in the middle :))
(Here's a great start for physical lighting, if you have trouble setting this up let me know and I can give you some pointers, the information unfortunately is all over the place for this)
