For a new scene, I have been working on a peeling paint texture. What do 
you think?

Nice.
A bit too much peeled, assuming the paint is red.
The cracks are fine.
can you reduce the white big area, while keeping the cracks ?

The code is a bit messy at present, but I work towards a macro that will 
enable the whole range. For instance this image.

A first version of the macro would yield this.

lovely.

The red is paint... crackling, peeling. So real.

The green might be interesting for moss if a quick gradient is available
at the boundary... give me a finger, I take the whole arm!

My final macro (for the time being?) gives the following output. Paint 
can be peeled from 0 to 100%.

I shall post the macro in p.b.s-f. Usage is included.

Enjoy!

To me, moss would need a different kind of macro...

I have not done it (yet) but you might want to use the macro in 
combination with a proximity pattern.

The cracking looks great.  It doesn't look like it's peeling, though.  (PeelED,
yes; peelING, no.)

So, improve it. Thomas has given us a starting position.

Don't criticise, improve

Thomas asked us what we think; what was I supposed to say?  In order to improve,
one must know what to improve.  But the way I saw it, this is Thomas's texture,
and I was leaving it up to him to carry it in whatever direction he desires.

Racking my brain a bit, I recalled the cracked mud in "Age of Innocence"
(Cathy's World).  Perhaps the peeling effect in that texture can somehow be
merged with the cracked paint texture.
