Hi here my tips, as you are still practising.
1. Fix the mapping.
2. add some retouch in PS. (Auto-Colour will work wonders here).
3. Lower wood bump
4. Add chamfers to corners or use the material option for that.
5. Highlited area on windows theres some light leaking in.
6. Camera Correction Mod is now your friend.
7. Light plug needs fixing.
Cheers
