nice work, honest is right though 1:10 is a bit long for what you're rendering.
Did you use the portal light or did you just slam a full sky on it? ( which means it samples your entire scene( so outside as well).
Did you tweak your render settings or did you hit the "production"preset in Mental Ray.
I do not know if I can stick to it, I mean is to find some CG work, but it is not easy.
I love fishing, very interesting and a moment of calm, and then back to my work, always looking forward to do better. Huh, huh.
