This is not a complete review.
First off, the title should be Cambodia UNESCAP / ASEAN Asian Highways, since UNESCAP does not recognize AH123.
Anyway, it looks pretty good, but I see the following changes:
AH1 should probably bypass Kampong Chhnang (the old and new routes are both signed as National Road 5 (https://www.mapillary.com/app/?lat=12.269462&lng=104.606239&z=17&focus=photo&pKey=574317931427387)). I'm not sure about Oudongk, Battambang, or Sisophon, but all bypasses are designed as the thru route at both ends. But then there's this (https://www.mapillary.com/app/?lat=13.58798299999998&lng=102.96813199999997&z=19.19217285619203&focus=photo&pKey=711103964085552) in Sisophon, so I guess keep AH1 through town unless there's a good reason to assume this sign is no longer accurate. All of these bypasses are mentioned in a 2015 presentation (https://www.unescap.org/sites/default/files/Cambodia_13.pdf) about Asian Highways in Cambodia.
AH11 needs several points at E4 (https://www.google.com/maps/@10.6062094,103.5821719,3a,39.9y,124.92h,100.54t/data=!3m6!1e1!3m4!1sAF1QipOvm0k15jU71TFgmzNAT_7pNAbt0Qv5Uym_3_YE!2e10!7i1920!8i1080?entry=ttu) interchanges. Unless AH11 uses E4?
AH21 has a potential bypass around downtown Siem Reap, but I'm not seeing signs for anything.
