C'mon.. No activity in the last month is not a big deal. On my github[1] I have periods where I go for months without committing a single thing, and then I'll have a flurry of activity in the course of a week.
People have lives outside of coding and sometimes they go a month or two (or 6) without pushing anything to github, it's not the worst thing in the world. I mean we're looking for quality of contributions here, not quantity, right? To me a bigger 'red flag' would be that all the django code seems to use function based views (not class based views) and doesn't really have any consistent formatting. OP I'd suggest skimming two scoops of django[2] and reading PEP8[3] so that you can get a good idea of how most shops write their code. Either way, I think your projects are mostly great and show that you're actually able to build things.
