Many thanks for your kind comments, I really appreciate your support!
@ Janner: The castle is scratchbuild by me using foamboard and cardboard. By now only the first segment is finished (a tower and a wall-section) - I'll post more of it when it is nearer to completion.
@ Emir: Yes, both the Rohirim-horse and the knights of Gondor horses (for the Military Order) fit very well and give a lot of variation. It also adds stability, as the original Perry horses of this range are quite fragil and have very thin wrists.
