Hi All…
Maybe i’m a little bit late with this sketch, but here we go:

-
This sketch is just composition and values.
I was trying to use both sides of the plate, but was stucked in a simetric composition. Then Brian came with that beautiful concept using just right side of the street and it was ok…
This gave me much more freedom to create the valley i had in mind, and it’s represented in this sketch. -
This is an homage to huge canyon we have near home and i wanted to set huge scale as well. It follows the river and makes a curve to the right in the far distance…
This huge scale makes the portion of the plate maybe small… i don’t know if its ok, but i really wanted to show a big and vertical canyon. -
I also want to play a lot with shadow an lit areas. A big canyon, with big shadow area and the river cutting it all, as if it was bleeding…
-
Outside the canyon, in the top, there is a desert. And the dunes ends in the very edge of the cliff.
-
Architecture: I didn’t define yet, especially the palace on the left. Now i’ve marked position with some city of pietra reference (Indiana Jones). But this is too greek/roman style and i don’t like it. But the idea is to put some religious or mystic palace there.
It’s very important for my composition as i want it to guide the eyes from palace to the balcony in the other side.
Actually i think i will pick the mood of planet Tatooine, with houses sculped directly on the rock. The only materials this people from the canyon have to build are rock and iron/brass.
Many scaffold elevators, stairs, ropes, chains, but no bridges in this valley, as they didn’t have developed engineering to build it.
Well i’m looking forward for your thoughts and comments. I have no words to describe how good it is to follow the forum with the contest on. Such great artists (some of you idols i must say) giving such good feedback… it’s priceless ! And free, by the way. 
Thank you all guys for spread the knowledge and share your keen eyes.
all the best,
Norberto
