I was on the net the other day and came across a few drawings of different Trooper costume variations and saw one that they called Aquq-Trooper and noticed how closely it resembled a Scout Trooper except for the oxygen tank and flippers and so I decided to give it a go as it was a nice simple custom to do.
When the figure and base were completed I painted it using Vallejo and GW paints
Body - The whole body is a VOTC Scout Trooper all I added was the oxygen pack which is from the concept Bobba Fett, oxygen pipes which are some left over ruber tubing from and older figure and the flippers which are made from plasti-card.
Harpoon - The harpoon is made up of some older SW rifles I just cut pieces apart and put together till I got the desired look.
Base - The base is a GW miniature base it was painted with Vallejo Tan once dry fine sand was added. Once the sand dried I got a few stones using kitty litter placed them on and the seaweed/grass are fish tank plastic plants painted and drilled holes and glued in place.
