Thanks a lot for your comments, guys . I've cleared the horizon line like willf suggested and it looks much better . Now about the sky : i want a very clear tropical sky, so i have completely deleted the clouds . And now it looks very, very empty ! So i will add some seagulls, and maybe a few more flying birds ( what do you think about penguins ? ;) ) . Well, the main problem seems to come from the scale, as Azchip noticed . I've improved the water, the island and its shader a bit, but it will not be enough ... I'll try the palm tree idea . Anyway, i will post the scene in the gallery when finished . Thanks again . litst litst.@freesbee.fr
