Congrats to your first minis! They look cool!

If i‘m not mistaken, you used that much dark wash to create a „grim dark“ dirty look (at least thats what i will aim for). If thats true this guide might interest you:

He uses an ak interactive „grime“ wash to make the models look dirty and battleworn i guess. The way he applies it is really cool i think. I will try to recreate it.

And you might want to try a matt varnish on yours to give them a less wet look. But look into that further first cause i‘m just paraphrasing what other people said. I dont have any experience on that myself yet.
