The first improvement:
This is a modified texture of the note, both the one that comes out for reading, and the wall now has details.
A bit of a short laboratory, since it only plays an intermediate role and gives a little idea that Fritz is not as simple as it seems.

There are more details
Nice ! but maybe the green half life texture looks like so much to half life and would be better to change it by something else
