Howdy Olivier,
Your VT72B is looking great. What scale is that? I don't remember a kit of this vehicle in 1/35th, but then my synapse's aren't what they used to be.
As you say, the pics are a tad dark, but from what I can see she looks fine. If you're looking for nits along with your 'atta boys' then the thing that stands out the most to me is the 'slack' in the crane cabling. I'm not sure if you're using the kit supplied cable or not, but just the sheer weight of the block itself would pull the cables tight. So maybe replace with wire instead of what looks like thin rope.....
Any other comments will wait until you weather.
Keep up the good work!
Tread.
