I like this picture! wish the rainbow was more clear/sharp... but the idea of puting the rainbow as the road was great!! I just cant see what this has to do with the quitting thing... im really trying to see it (Because i think the composition is great...
Nice angle, great positioning so that the rainbow seems to coincide with the bend in the lane. Not sure what this says about quitting though, unless we are to take it that the shadow in the foreground is someone keeled over from trying to find the elusive pot of gold.
