but there’s things to fix.
can u point me to any? i checked and can’t see a wrong in it.
Would love to see more variation in the grass, maybe play around a bit with the various random and threshold amounts. Also you could model some different types of grass and distribute them, but that’s quite optional I think 
I really liked the bushes in some of the earlier renders, but I guess they are not fit for architectural visualization.
The lighting seems a bit weird to me too, but I can’t really put my finger on it, I’ll leave that to someone else 
different types of grass and distribute them
actually there are 2 types and they are hair systems, but i get you it is very formal -which gives a special tase- i’ll play with and see -iAw-
I really liked the bushes in some of the earlier renders
yeah, but they felt like out of composition, so i decided to del them.
Yeah, they probably were
My thoughts: the vignetting effect is too much strong; the sky is dark/too much blue compared to the light arriving to the house; i’m not sure if the ivy can grow directly on the wood and walls, without soil.
Anyway if you are looking for ideas about grass: http://www.cgarchitect.com/2013/11/inspiration---trees--foliage-vol-4 or this for more: http://www.cgarchitect.com/features/category/inspiration . Here there are some of the best renders i have seen regarding architecture 
the vignetting effect is too much strong
yeah maybe it needs fine tuning.
the sky is dark/too much blue compared to the light arriving to the house
maybe this too.
and i visit cgarchitect regularly, they have -out of my league renders- and i’m still a WIP, hope i’ll someday reach there -iAw-, but thank you.
i’ll see if i can render a new one soon.
here is an updated render with less vignetting, brighter sky, more varying grass, and a connected ivy:
you’ve done very well on the house itself so I guess you’ve accomplished your goal but you’ve post-processed this way too much and the grass underneath the house looks horrible, you should try making it stick up more so it doesn’t just look like a texture.
grass underneath the house looks horrible
i thought so too :eek:, actually i cut it more than i should.
