Rejected.
The current builds in your application are not the kind of quality you need to become a builder. Look at accepted applications for reference; however, there are a few applications that shouldn't have been accepted that you should not refer to.
Circular builds, builds with abnormal shapes, abstract, and large detailed buildings are all good things that will get you accepted.
Examples below:
Circular build with detail
Large building with great detail to it:
A build with abnormal shapes to it:
Build with good detail:
The spoiler is an example of how I went through the accepted applications looking at good builds other people have made. You could then use those examples to make something just as good; but don't copy!
Good luck.
