look at me!

I never thought I would post one of these types of questions but I need hair help nao! I'm feeling hair-impulsive & trying to decide whether to lighten it to blonde or to leave it alone as it is now,which is brownish/reddish. Examples of both hair colors on me are below the cut...

With the blonde hair...


 

And with brown hair...





So my vain image-centered question is...
what should I do to my hair??!?!
