I agree with the comment about the stripeyness of the shading, especially on the legs.

However, I think part of it is to do with the colours you've used - they don't seem to form a logical sequence, with one almost being blue and another being very pink. i think if you simply adjust the colours so that they're a simple sequence it will work better.

A way to determine the colours to use would be to take the colour you want to start with and the one you want to end with. Then, in a separate document do a linear gradient between the two. Then, if you want to do 4 stripes you use the colour pick to pick the colours at about one-third and two-thirds distance (plus the start and end colours, obviously makes 4 bands).

Although, tbh, you may want to rethink the colours in that respect anyway - you've got some extremely light shades going to very dark ones so it will always look strippy unless you use loads of shades. Try experimenting with less sever shifts - make the "to" and "from" colours closer on the pallette.

An alternative technique would be not to use separately coloured layers. Instead, if you make the shade layers increasing darknessess of grey and then set them all to overlay/hardlight/softlight or whatever you will achieve a similar uniform effect.
