not far, as it has been decade since I have last build something that complex, I have chosen to first recreate the upper section, to understand how the exterior and interior are made (through my understanding of course:) ), so I'm done with the top section of the hull located to the back of the ship (the part beneath the command deck). Progressing from the top to the bottom is kinda uncommon and dumb, but I know I'll have to build/rebuild/build/rebuild anyway, so I did it the way I felt it ;)
And even if I do have a load of parts from previous things I have build, grebbles wise I had to order several bricklink orders, and since I'm in Réunion island, things are slooooooow when it come to ordering from outside, so I need to be calm, like really calm when it comes to handle the waiting lol
