That actually looks very good even if it didn't turn out to be the all over colour that you were hoping for.

I've been dying my own hair for a long time and it took a bit of experimentation and a bit of stubborn persistence to find a colour and brand that worked well for me and I have the opposite problem to you - light coloured hair rather than dark. I'm pretty sure that I've gone entirely grey now but my original plan of letting it all the dye grow out at that stage has been shelved because I still like having black hair enough to go through the regular process of doing the dye job.
