Thanks for the tip, but I already played a bit with the lines. You wouldn't want to see the raw image. And even after that it's still too pastelle and actually I doubt that anything can be done about that, at least not by me

Some may like it, bah, even I don't think that it's totally shite, but it isn't the effect I wanted. But whatever, what can you expect from the first image did in the greyscale anyway.
I'll try playing a bith with the cel shading and lighting in crucial spots, maybe I can get a better effect with the small help of the screen and multiply.
About the tilt, indeed, you were right, I wanted to show the struggle against the heavy wind but I overdid it. 10* was enough tho.
Thanks.
