About the directions i dont have any problem, i know how to change the texts. I select it with Polygonal Tool and then Alt+backspace and the text dissappears and i put mine text.
About the smudging and blurring. About these i dont know almost nothing. If you have any good tut send me in pm.
And about gradients maps. I dont how to use them, so if you have again any tut send it to if you can. :D
Btw, i hope you liked the image. I will try to make more images with THEME and no sings without ANY THEME, just only a render and then you handle it as you want. The real photographers make images with theme and that is what i try to do.
But and the signs are inderesting.
