L shaped layout

[railbashernovice]

Hi all
with this layout design in OO gauge I was after having plenty of sidings instead of a fiddle yard and I think I have achieved that aim. I was also aiming to have a decent sized station running along the back wall. I am open to suggestions or ideas on how I may improve on this design

Do you have walk around access from both sides of the main section?
