Great job mate - and the masking? Rather you than me mate!
A little tip if you want a 'soft' edge and don't have an airbrush. This works up to 1/32nd scale, but is time consuming !
Mix together 50% of each cammo colour, example, 50% Green + 50% Sand. Then, depending on scale, use a 000 or 00000 brush, and paint this, follwing the line of the demarcation between the two cammo colours. It gives the appearance of soft overspray between the colours, especially after the gloss and matt clear coats.
