Very nice! A big model too!
About uploading pics on the forum: there are two icons for pics in the message writing menu, use the first one on the left ("Héberger une image") to first uipload the file to a server and then copy its address in the message. The first time I believe, if memory serves, you'll have to create an account in the image server service. After that it's the same two-step procedure for each image.
Again, well done!
