Great chapter! Now you only need to create your armed forces, expand your population, and improve the living conditions even more. You should also give gentle and svenn positions of command, bodyguards are ok, but I feel they deserve more.
No need to go back, your story is just that, YOURS. But, I think this is an opportunity for you to write about the growth of the mc as a leader, dragonborn etc.
Really hoping that our mc makes his friends his thanes, it's the least they deserve. Or his vassals if he's going for the westerosi way.
As for your question in the previous chapter, I think that he should marry either aela or sansa.
