Thanks guys for all your comments !
So, last day for the landscapes competition ! Mine is sadly not finished, but here is an update:
The construction is finished and undercoated:



(Here i have to add stairs)

Some stuff is still already painted though:



Mike, were you traumatized by Timon and Pumbaa ?



And i have all these accessories sent by Mike (thanks to you again !) to add:

What i still have to do:
paint the building, of course
add a flag on the mast on the top
do the base: sand, flocks, grass, etc
finish to paint and glue the accessories
Build wooden stairs to put on the rear of the largest building.
Stay tuned !
