I find this both awesome (it's an amazing style, it's Legion) and scary (the Red eye, the cluster of sparks in his chest).
The one thing i will say - it's not a criticism, meerly an observation - the N7 badge is missing from the salvaged armour. But that doesn't change the fact that this is a fantastic piece. It's the 'Spark-Heart' that wins me over the most, I just Love the 'Spark Heart'.
Thankyou very much. Indeed they can be difficult to do, and like I said before sometimes parts get missed. One of the best examples is my Kefka from Final Fantasy Artwork - "You're Only Make Believing" - only after I uploaded it onto dA did I realise I forgot his earings.
