Mass Effect References
You are free to use any of these model references however you wish; whether that be to create a costume, a prop, a piece of art, a photo manipulation, or even to create your own 3D models. You need not credit me or even ask permission for use. You must, however, credit BioWare/EA.
A more easily readable list can be found here.
If you haven't already, then I strongly advise to buy the Mass Effect series.
Since *Lordess-Alicia has linked me in her reference folder, the least I can do is like to hers here. Check out her other gallery folders, too .
