Great work! I think the composition is excellent, and I really like different levels you made in the terrain.
Since I know you are open to constructive criticism, I will offer this:
- The colouring of the terrain is very good, but it looks too much like a single mass. You can differentiate small rocks and sand grains by brush painting them with different colours to make them look like they are 'loose' from the rest. Light colours are the most effective for this. Uncle Night Shift shows it very well here (from 3:51 on):

- Many of the structures have gaps where they meet the terrain. You already hid some of those effectively with accessories (which is very good!

), but the other gaps can be removed with most putties or terrain mixes.
- Don't wait too long with finishing the sides of the base. If you wait until the end, it will be harder to get clean sides without damaging something.
- The junk yard looks great, but it can indeed use (a lot of) additional small parts. You already noted that; I just wanted to confirm.
Looking forward to the final parts of this great project!
