ok i will take them in consideration.
The brits surrender because they see they lost, they are bankrupt and their colonies would cost more than they could be useful.
But as many seem to be againsti may think about that.
The Baltic states and poland got annexed though, later there are revoloutions, because polands and the baltics want to be independent, same with the german colonies, most of them (especially the afrcan ones) start to rebell.
Hi,
sound better
i suggest britain make peace after the loss of the BEF and france surrenders, like poland and italy (or let italy out of the way)
russia goes down as historically, just a year earlier (without entente support in money this could happen)
so the cp won this war, dictate the peace
Belgium loose all colonies, germany get em
france loose its colonies, germany get em
uk keeps its colonies, give back the german ones or the germans just keep the soldiers as prisioners... something like "all colonies (including the ones japan and australia took) are given back (so the germans need just one passenger ship and show the brits the finger

) or the core of your youth rot in prisions... i bet the german colonies are given back faster as one can say "no".
after the victory the germans run into big problems...
the new countries in the east will in short time want independence... some (like poland (how surprising

)) will start a war and loose BIG time, others will start to get independence smarter...
the colonies the germans catched (and it look great on the map) will be a nightmare, very fast a lot independence movements (financed by the brits) start to make them unrest... some are given up (or given independence), some not.
the congo will again suffer...

, in south-western africa it will be calm, also in the pacific and eastern africa...
but the rest? they will go into independence, either peaceful cause the germans recognize they cannot handle them or in unrest and war.
serbia will be destroyed, maybe parted in 3 or 4 parts and some are annexed, some are given to other neighbours (divide and conquer)...
russia will suffer big time, again as otl, but the reds will not win - or germany will strike.
that could be such a scenario (as you want it)
you still have to explain why the brits loose, why the germans catch large parts of their army and why the french surrender...
