6.5 This is not bad the colour choices work well, It looks like you like to drybrush your skeleton bone colour this is not always the best way.
I find that a light drybrush to start just to define where the detail is and then carefully picking the various bone sections out. There is also something on his face it looks like a mould line but I may be wrong. You could do with some more highlights especially on the scythe handle and a dilute wash of brown and black ink on the scythe blade.
If you do these things then your score will definately climb higher.
I hope that I haven't been too critical as I am by no means perfect.
