Giving up on this one for now

Ok ... I'm giving up with this texturing of this wall.  I appear to be going round in circles.  I'm not a 2D person. I don't think I'm great at texturing however damn it I'll give it a shot.  I'll keep trying but today this has really got me down due to the amount of hours put in and the amount of s**t I got out of it lol
I think thats the latest render...
