Seeing the work that you have done, you are getting very close. However, the quality is slightly lacking still. A little tip for you-- use various textures in your builds, like textured pillars or something to that effect to make your builds look neater and more clean
And don't rush through your builds. Take as much time as you need to get them done to the best of your ability.
Rejected for now, but you are not far from a promo.
