Creating Conlangs is hard

Oh boy, I have bit off more than I can chew with the story I want to write. So my story is about a group of aliens called demarowls. They've lived on a climate ravaged, nuclear destroyed Earth fit a couple generations without any real signs of humans. The species doesn't have the same sex/gender set up as humans. Or even similiar anatomy.

When I gave my characters names none of them had a theme...and most were definetly humanesque. So I made a group of prefixes and suffixes that I can build a large variety of names out of and bam lots of cool layered names! But then I said, "Hey, the roles in the colony could benefit from this too!"

And I did that. Then I did season names since the seasons aren't the same as real life anymore.

Then I named the cermonies...

Then I came up with two words I thought were fitting. A greeting word and a warning call.

Now I'm running into the issue of what else do I need to make. Do I need to make more? How do I turn it into an actual language instead of wordsmash?
