That's not lorica segmenta, it is the armour from Poeni Infantry (I've done too much skinning not to recognise these things :p).
My advice would be to remove the crescent from the shoulders, and change the skin colour and face so it looks more African (You could just copy and paste it from a Libyan/Numidian/Eastern unit). The palm trees look good from a distance, but when you're close enough to see what they are, not so much.
