It is looking good so far. One thing that I would suggest is making the digital pattern less square-edged. That is going to sound strange but on something that small the squareness at the edges would be 'fuzzy'. In real life (life sized), you can see the squareness up close but as soon as the troops move off, you just see areas of colour and the edges blur into each other, giving a blobby effect.
On a major PLUS note, you have the mix of colours in just the right sort of spread and the colours you are using are bob-on.
