GREAT ODENS RAVEN! thats Freaking awesome..I think Ive wet myself lol, seriously tho one of my new favs! kinda makes me feel old tho. to think I played the very first Samus Prime and I can still remember the "Shock and Awe" to find out that he was a she. Good Times. Good work!
Fantastic work. Its always great to see her in a new and different light, which the black and white certainly achieves. Kudos especially on the face- I image that thats what Samus' expression is as she explores new worlds, that is wonder mixed with the ever present wariness for danger. Faves!
Second, it's a really nice green and I do love the emphasis it gives. Her gun (forgive me I know very little about Metroid and have no idea what Samus' weapon is actually called) does deserve the attention it gets thanks to the green as it is wonderfully crafted so I would keep the green as is.
Maybe add a splash of color to her face. Perhaps the eyes or lips? Just something to draw attention to it because it is really beautifully made.
