@PhilMaker : Not at all, in fact It’s because of the node editor, (the postprod) I got this effect, and finally It’s something I wanted, but maybe It’s not suitable. I thought that gives an effect more “magical”…
@Illusionist: Yes I want to print a poster from it, I haven’t rendered the right size for it yet. At first this image is at the moment only 72 dpi, which is not suitable to be printed If I’m not mistaken. So as I want this to be A3. I will need to render a 3508 px x 4961 px (300dpi). I have no experience with it but I think It will be ok? If I do that… If ever you have any suggestion about this, feel free to share. Maybe, I should do a little print test before, with the smaller render. Just to be sure the image doesn’t come too dark or something else.
@Nico: Thank you, you are probably right about the fact It might look creepy.
