het thanks Rui for your in depth answer

happy to know I am not alone struggling with harder than balsa wood. You know why I can't see a regular frame maker for my dio? hey, it's not square.. my resin manipulations usually induce a slight amount of warping, and indeed the angles are not at 90� but more 88, 92 etc..
happy you liked the spray! it's been done by applying Humbrol Clear Quote and then wiping it out with white spirit!
the diorama is absolutely 360� with a direction of light. Though there will be certainly a "prefered" angle vision coming from the fact the figure won't be visible from every corner of the scene.
here's a picture I took of an unusually angle though still from front):
I will also investigate your trick to recover wood later today -thanks for this
back to the diorama, I reminded yesterday about something; I love wrecks, I think they are really very romantic. yet the few times I found or visited some on the Atlantic coats, I thought there was something very repelling about them, like a bad aura or something. I realized this by working on the diorama again -that's this nail thing. I just added quite a lot and suddenly my galil�e wreck began to make that same impression on me, like something both frail and quite dangerous in fact.. i will have to search a bit more words to tell about my feelings towards this.
But as you can see, a few nails on details can really change quite a lot of things..
there was something about the diorama I wasn't too happy about: there was not nearly enough of sea near the Blockhaus, so i had to change that. But then that would mean put some chunks of resin near the metal and that would have produce some dreadful result if the resin began to leak on it.
So I used a very old trick to do this: I dipped tiny bits of cottonwool in the resin and placed them at the right place. They have the right texture for that.

then 2 days ago after the resin set, I added a biot of foram to cover the joints
then another thing: I realized that the mast was standing too clse to the cabin. So using 'carfelully the powertools and sheer muscle strength ( %) ) I de-embeded the mast and changed its inclinaison in a more suitable position.
I could clall the diorama finished except for the fig, but then I will add a bit of rigging to the mast which will help trace other lines on the scene..
