Just a little something I did for a tutorial.
Any constructive ideas?

Yeah. Turn it into a city like in District 9.
looks very good 
you should see about adding it to a larger scene or into some still images 
Simple, but nice. Nothing really wrong with it.
Think if it were pissing cats and dogs out, would look even more attractive.
Usually shacks like this would have walls of some sort. Most likely plywood, sheet metal (like the roof) or even planks.
Other than that it is really nice! Well done.
