Screen print image preparation

I have been working on an image to screen print in four colours, this is “Tread Lightly on the Earth”, an image I first drew years ago but have returned to.  The watercolour original is quite large so I had to scan in several A4 bites and reassemble in Photoshop.  There was no colour consistency from one scan to another so quite a bit of work needed to get it back as I want it.  But once this was done then further manipulation is simple.
