gmillereight:i couldn’t finde WH30000 pics :s post a few if u have, plz!
arturro: excellent, when i was making the colour sketch, there was something on the background that was anoying me, but i didnt see what was it! u r right! but i really like big clouds… so, i think im gonna reduce them a bit, and make vertically larger the final image, so ill have space to play with the sky and separate better the fore and the background (maybe i could desaturate a bit the background, or changing its color balance, makin almost an unique tone… ill see) thnx!
BC “mil nueve sesenta y siete” :D: yes, i was thinkin on it, pushing more the angle not only will give me a more detailed view, i think it will bring more power to the scene, but for the colouring sketch i didnt redraw the scene, i used the old sketch and painted on in
too lazy and short of time 
worleyclarence: i didnt understand the question :s
greetings!
