Here is a modified version of durands:


That's a lot better, I appreciate that you gave it some depth with the dropshadow. That's a big improvement over the flat graphic, which I think would look out of place on today's desktops. The alien/human dynamic comes out well in this icon.
I have two suggestions. First, find another colour for the "T", one that contrasts well with the red and blue sides of the icon, without clashing. Second, and this may be argued succesfully against, see if you can add some depth to the shapes by employing gradients to give it a more 3D feeling. Of course, this would make the icon look less like the HUD icons, but it would make it fit in more with the contemporary style of icons that are found on most desktops.
