Blog has been a bit quiet, but I have not. Amongst other things I've painted up this rather large castle set. It is from Renedra and is their "Small Castle"(!) set. Small compared to their larger castle sets perhaps but quite large enough for me! I've added two ruined wall sections and another tower for some options.
I did not buy this castle specifically for Napoleonics (and especially not the siege equipment below!) but it may well see some use for Napoleonics as there were many sieges or assaults on forts or walled cities during the Napoleonic period.
For inspiration here are some pictures of Napoleonic Siege Warfare.
And for the ruined wall section I did a similar process, adding some cork and greenstuff as below.
