As I have no courses at university today, I used last night for painting and was able to finish the Predator.
The result after applying the pigments was somehow awkward compared to the other IW tanks I did so far. There must have been something wrong with the top color layer I airbrushed on because it stripped a little bit. Or maybe it's just because I'm out of routine as I haven't painted IW tanks for quite a while...
The Predator did not turn out that bad, though:
Some of the human scum's clothing has also already its paint.
