Composition: Really like the layers and wave of the skyline
Technical: Fantastic focus and colour
Meets challenge: Yes
Overall impression: Can't help with wishing the cloud wasn't there.
The cloud shadows are interestng - I'l have liked it if you could get the clouds in the shot as well (not sure if it was possible - not a criticism, just a thought). I like how all the lines flow to the centre, so for that reason might have centred the house, or made it more off-centre. Being *just* off-centre makes the viewer wonder if it was intentional or not.
