@ ECPixel - thanks for that, I forgot to double check that there weren't any outside the template by using a clipping mask haha XD Fixed that now : )

You need a lot more contrast in your colours, right now the colours are way to soft and the whole thing feels out of focus. Also try some hue shifting by pushing the shadow more to a purple and the highlight to a yellow etc...

Also neck needs more shadow..

Also I'd avoid using pallet generators as the tend to be pretty bad. Observe some of the other pixeljoint members for ideas. Especially take a look at Dawnbringer who's great with colours.

Remove few pixels, you have gone beyond the borders of the canvas. Maybe you should make the colours more contrast to each other, they are too close in tone.
