Creating even a short cohesive story can be a huge undertaking, let alone doing so in 48 hours, so good job for attempting. I personally felt like the decision between truce and no truce was to morally black and white. It's not unrealistic for a truce to happend, but for a choice to be more impactful, there needs to be an extra factor like a higher command, lack of supplies, death of a friend or something like that, which would make truce seem like a bad decision from character perspective. That's just my opinion though.
Also I liked the artstyle a lot, it seems familiar, but I can't quite remember where have I've seen something similar.
