hi,
i think your perspective is bad? the horizon is higher than the point of convergence perspective.
generaly nice 
your perspective is actually fine
Curiosity wants a higher elevation render, so we can see what else you did in the image. 
Great work.
I like the current perspective, but I still want more…I know…I’m impossible to please. LOL
like it all… especially the grass! how did you make it? do you have a tutorial?
Thanks all for the comments!
Yeah, the perspective seems a bit weird in the right of the image… I saw it so many times I didn´t realize it.
@tc2466: Thanks! Actually just the house and the grass are 3D… no much more to show. Maybe I get inspired and make another images, but I confess I am a bit tired of this project.
@m_squared: The grass is Hair particle system. I just followed the parameters in Blender Wiki to achieve this result. I also made a weight paint to have a small variation in the size of the leafs.
great work
