Detailed windows on a solid gray walls =/ Huge conditioneer at the right of a climbing-stair??? And stairs on a roof are smooth, so they looks like a cylinders. But there are details! Good.

Crit:

1. Why is the grass around the building one colour while the grass on the other side of the road, has several colours
2. Your losing your outline around the shadow, if you look closely, you can see holes, just add a new colour.
3. The road is too small

Comm:

1. I love it
2. You picked a nice colour for the grass, sides, windows etc.
3. I like you tree
4. I would like to see more detail. Keep it up
