I'd give it a 5/10, nothing really spectacular that I couldn't make in 10 minutes, but at the same time it appears you put in more effort than the common-day blockhead, being that the latest people / builds I see in game are literal spam.
It's only good as a first start. Otherwise, almost below average...
Similar to what dark said: brick pattern inside and out doesn't work. Use wall paper inside. Your railings could literally be stepped over, raise em up. Nobody labels a crack house prominently. The only thing really MAKING this is a crack house is the sign, there isn't really any major evidence of drugs / paraphernalia going on with this build. Also, even if it's a simple lawn, some yard or street can really add to a build.
Keep trying.
