clean and simple 
Good job
however, you should pay attention to your perspectives (i.e. the TV stand and the heart walpaper.) And I see you named it "prohouse" 
tis big. lol.
Good job. You have alot of art in your gallery.
it's a good piece, it shows talent and a basic understanding of iso pixel arts, but I think there are a few things that should be tidied up.
the horizon on an iso piece isn't usually seen as you're required to look down on the scene in order to get that perspective. but seeing as that sun is looking very happy.. you may want to keep the sky regardless. in that case.. the horizon wouldn't be constrained to the 30% angle of iso pieces, and would look a lot better horizontal, just make sure it lines up, your horizon isn't quite matching up on both sides.
some of the curves, like on the balcony could do with a bit more practice to get them true. if you need some reference try using the 'skew' option in MS paint to see how circles behave in iso.
other than that, a bit more consistency with the black-lining and fill in the area of wall under the desk and you'd have my thumbs up 
.
