Very unusual but I agree 100% with forum.
If you stick to one country then we would be able to fill in the what's missing.
I assume you have checked flights between places and not made assumptions

Personally, for 3 weeks you should spend time for traveling to Vietnam only which will better than travel to Cambodia as well
Agree with previous posters. Stick to one country. If not, remove Luang Prabang. I love the town but just heading to Laos for one stop is wasting time you could be exploring elsewhere. Battambang could be missed also.You'll need minimum of three days in Siem Reap if you are planning on going to AnkorWat.
HCMC 4 days including Delta
HoiAn 3 days
Hue 3 days
NinhBinh ??
Hanoi 3days
Halong Bay 2/3 days
Siem Reap 3 days
Pnomh Penh 2 days
boat to HCMC
That takes care of your 3.5 weeks and only touching the highlights in two countries

3.5 weeks for so many places in 3 countries is too short, you should perhap spend your whole trip in Vietnam or Vietnam & Luang Prabang
