You did a great job, don't doubt yourself. To me just a few details seem a bit 'off'. Still looks very nice, but I'm very detail-oriented when it comes to pictures.
1) The main roof, you seem to have overlapped the sides on the center. It should be the other way around, the sides go under the center (like with the porch) That way you see the finishing on the edge of the top from the frontal view and it will give a nice detailing there.
2) I think this one will be 'unfixable' but the balcony actually has a sloped roof, not a flat one. This may make it look wonky in your eyes. However, the only way you can fix this is with half hipped/gabled roofs, which do not align with rounded corners so I guess it's a toss-up between the sloped roof or the rounded balcony :'(
3) The windows are blue, not white. If it were me, I'd settle for a less detailed window that still had the pop of blue, it will give the house some life. You could instead keep the white windows and add some blue curtains inside, that should also do the trick I think.
Either way, kudos on the great job you did on it, I bet some landscaping around the house will make this look incredible! :)
