nice one. nice textures.
but u cud use more practice.
The ground texture is not to the correct scale.
Lighting needs Attention. if i am right, u r using Physical sun and sky which is not advisable.
Light manually to the desired mood.
Doesn't feel correct time and weather in the lighting. compound wall in the right side looks just combined with the house wall and seems no distance between them. better lit that wall with a fill light from behind to get the depth and to separate from the house wall. the lighting looks flat all over the image. i think the objects(compound wall) near to the camera must be brighter than the far objects(house). i am not a lighting artist, i have replied only with my opinion...
good start go ahead...
