Fails

So i'm working on this project, set up the idea, render till dawn, get a nap. Upon reviewing the renders, i realize they are far too dark - no worries right, i can pull the save & change the settings (i dont touch photoshop). But of course, my saves werent the final versions of each render, just some early stage of the composition - when i remembered that the save button existed.
The work aint really lost, and you get to see the failed ones, lucky you; but all in all, i'm glad to be able to reshape the begining of the serie (10-15 img)
