they just seem a bit too "tone burned" for my liking.
just my .02, but i have noticed that the tone mapping on your projects tends to go to the extreme.
i'd be interested to see what might happen if you brought it down a notch and worked within the parameters that were meant to be more natural looking, just to see what might happen.
just a thought.
like i said. my 02. its a preference thing. over tonemapping makes things look very cartoony to me.
not meant to be discouraging. all effort and tastes ultimately appreciated as being another perspective as valid as any other.
