Yes, indeed, very good work ! Nice lighting, great music, etc...
The dark lines around the water's edge Janaba mentioned puzzled me too.
It might be caused by the UV mapping for the decal - see the picture below...
I exaggerated a bit the distance from the border - avoiding the picture's last pixel is generally enough.
And wow, Ainia, now that's a good catch ! The symbol blends really well with the picture, but it does looks like Tweek's logo.
