Hi there,
There is very little feedback so far so here is my two cents. Despite the fact that I'm not ArtR/Studio user there are some universal hints you could follow to get even more realism from your scene.
- almost every rendering suffer oversaturation, take 15-20% off for a start
- try to avoid elemetary colours in your scenes, since everything interact with everything you will hardly ever get solid red and yellow shrub with deep blue sky
- it is extremly important for realism that you make texture follow the geometry (pool) and vary it to avoid repetitions
- and the last and very subjective thing which I think many renderings lack is MOOD. It is not essential to sell the idea but it distinguish good rendering from just a colorful picture.
Bottom line is: nice work and keep on posting.
I let myself mess with your scene to show what I ment.
