My favorite Creation of yours!
I probably will start making a new series of MOCs/Dioramas on the Ice Planet/Blacktron II Clashes.
By the way, If you like Exploriens, you should check out this series: http://www.mocpages.com/folder.php/7675
I like this ship because the wings, connected with Technic pins, give an interesting shape. The cockpit opening is different too and works well for easy access to the pilot. Perhaps some tiles on the side would smooth its look? You've really stuck to Ice Planet's restricted palette but that has helped to produce a ship which looks good.
