vector, mesh fil, rendering effects.
Thanks, Ville, for your comment. Only pitty that your critique is not positif like: "to get this effect you better use another tools like..." etc.
Nice, although it feels a little "randomly" meshed at times. What also bothers is how most of the scene is quite dark. You propably wanted it to feel like it's in the deepest parts of the sea, but it's not giving me that effect. I like the coloring.
