Yikes, where to start.
Add a little variety to the shape of your hotel. You can hardly admit you see many buildings aside from houses and gas stations that are just boxes. Secondly, don't use JVS windows. As much as they would be nice to use it takes the challenge and creativity out of a build. Make your own windows for more credit. Thirdly, add more windows. Hotels in particular have windows in most every room and by the looks of it I can safely guess yours doesn't. Then, don't make the build so spammy. Learn to use larger bricks and to not overuse those. Also try to make it so the exterior bricks line up. I don't know how else to word that, sorry if it's vague. And lastly, you need more clearance. Hotel ceilings aren't so short you could touch them without even trying and the pool is usually not above ground.
