Hi. :)I am not an expert at all.But the lightning is the problem because it maybe creates (you know better) so many dots which are noise? It is very obvious, specially on the fence.If you work in archviz area, maybe you should put a woman instead or a couple - cause those are things that attract people rather than a common man walking by. On the second picture there is a small detail - it looks like the chimney from the background object is intersecting the wall.Apart from that, everything looks great.
