I'm surprised you survived that.
Anyways, theres not much in the build, if it's 5 bricks high, I suggest making it higher.
Look closer, it's six. :O
I'd definately suggest doing what he said, though. For a build on its own, a 19 heigh is not typically acceptable as a good build. Also, don't use a blank wall. It's good that you used a different color for the baseboard, but that isn't good enough for a good build. If suggest using the vertical print plates that add depth to the walls. Also, splitting the wall height in half by using different colors and a separating color makes a build look more detailed. By adding vertical beams to the wall where the larger wall bricks meet make the wall look more realistic because walls typically do not have lines on them after painting where the drywall panels touch.
Look at the ceilings, too, because those bottom textures always look terrible in builds. Eliminate this ugliness by using upside down print plates to make a matte finished ceiling.
