A little bit simple but is ok.

1. Strange lighting of edges - especially on left of the roof. What the white stripe?
2. Weird bricks looking like a... not like a bricks.
3. No shadow on a window.
4. Flat windows and doors.
But fot the first ISO it is not bad =)

Thanks for the critic, i will consider it for the next time i do bricks, by the way, i just did them like that so they match with the isometric view. Thanks , anyways!

I like it  The shading is good but the bricks are a bit funny to me- IRL they're more like:
___ ___ ___ ___ ___ ___
|___|___|___|___|___|___|
|_|___|___|___|___|___|__|
|___|___|___|___|___|___|
|_|___|___|___|___|___|__|
But in your pic they're just a bunch of squares on top of one another... Structurally unsound  

Also, one thing that stands out for me is that the windows and doors aren't recessed- check step 2 of this
