That's a gorgeous snake and I nice looking setup .
Given your snakes colours ( light ) I would consider swapping your light coloured (aspen) for some Orchid bark chippings which is very dark in colour and emphasises the colour of the SNAKE..
Also I stopped using aspen as it gets all over the carpets and drove the wife bonkers . Aspen sticks to the snakes and water dishes / branches when you're pulling them out of the viv .
