And welcome to me!
I think this is not the place where to make compliments to your mothers to have made you so prolific; isn't it? 
so I'll make you compliments for all your creations; I think the pattern of the flagstone is very impressive (impressed even me!); who did it? faber or calopide? well done.
how about this :

for the central part?
bye!

welcome Tom! Kritikor is a friend of mine (well, I'm probably more related to his mother, but that's another story

)
Thanks for the compliments mate. The pattern was sculpted by me and Calopide in randomic proportions. It's pretty easy when you find out the way to do it.
About the central part, a Scaligeri's ladder is a wonderful idea, knowing my passion for them.
BTW I'm glad to see you here on LAF. It's a modelling goldmine, trust me.

cheers
(see you on 23rd or 24th)

How about using something similar to Kritikor's suggestion but replacing the initials with your own? 
Nice thought mate! In effect it could be a good chance to "sign" the entire project!
