Honestly, I think the game is at a fine level in the graphical fidelity department. There's already a thread about how the color saturation has gone overboard with the current patch and I agree it should be tuned down to what it was in prior patches. It was realistic, but also natural in a colorful, vibrant sense. There are certainly somecartoony elements to the graphics, but I'm not sure the picture you gave as an example really portrays them. To me the BG3 picture you showed looks perfectly grounded and reasonable. Frankly, I think it's the story elements and occurences in game that threaten to be too cartoony, moreso than the graphics.
