I hope you’re not too tired of these walls.
I wanted to draw a last one.
With some stronger lines on the wall.
And lighter on the background.
To see if it gave the drawing more depth.
Well, here it is:

I guess the lines could be even stronger – and weaker.
But the differences made the drawing just a bit more interesting, I think.
I haven’t really used this as an effect in my drawings before.
So I’ll keep it on mind from now on.
Anyway, I hope you are doing alright and having a good day.
