This is very easy way to paint look like to old log!
Need some base color some wood brown is good.
Then i paint neutral grey. it can be painted carelessly. It's better if paint is unevenly.
Old log needs some cracks.
Then i use black panel line accent all over old logs, Its absorbs black every crack
Last step is dry brushing some very light color. I use lifecolors wood cold light shade paint.
If some parts go too light or cover details you can use again Tamyia panel line accent colors.
Old time is very typical use moss from insulation. And this give nice details to old logs!
I hope at you like!
Thank you for watching!
