My First Crochet CAL

So, I am currently trying to get organised for a Cal. by Polly Plum and it is not an easy task.  You see I am making it for a gift and to be honest I think it is above my crochet level.  This is what the finished product would look like but I have chosen different colours.

 (This is not my picture and should anyone want to have a look or buy the pattern click here.)

The colours that I have chosen are these. next step is to try and figure out what order to put them in.

and this is what I have come up with.  Now I am not of sure of the colours.  Is it a little dark? Thinking I might need to change the outer grey to the light grey or mix it up totally and use the cream instead of the green and the light grey can be green and not use the darkest grey at all. umm decisions decisions.

This sample here only took me all day to do, Unpicking or Frogging as it is called in Crochet and redoing.  I hope it get easy lol

Edit: This is what I finally decided on for colour choose.
