Texturing Help

Hello, i need some tips/advice on how to texturing correctly. I made a hangar and textured it in blender with pbr materials, created uv‘s, baked it down, created a composite and so on. But at the end my textures seems to be washed out. I baked it down to a single image with 2048x2048 and it does look bad.

When i look at other airport from like gaya, orbx etc. they all use most of the time 2048 by 2048 and even have larger buildings on the map (uv) but they look crispier than mine.

What do i do wrong? Am i missing something?

Help would be nice. Thanks in advance!

In my opinion the substance painter is the better way to make msfs Textures.
