New icon for Near Infinity

Near Infinity uses a dated low resolution application icon practically since the very beginning of the tool. That's why I'm thinking about replacing it with a modernized version or even a completely different icon.
 
Since I'm not the most artistically skilled person, I'd like to ask you for ideas or samples I can use as the new application icon for Near Infinity. The icon should preferably be 64x64 pixels or larger.
 
This is what it currently looks like (magnified version):


 

To start off I'm presenting my own creation, which is a modernized version of the original (in different sizes from 128x128 down to 16x16 pixels):
 

 
I'm looking forward to your suggestions. (Edit: I have posted the same topic here.)
