The sidearm in there looks kinda nice. Maybe. Everything else is just...
. Especially the animation.
Why the hell would you make a (more or less) anatomically correct human character look like they have some bracelets, anklets and a layer of body paint on for wardrobe and then give them an animation set firmly in the Uncanny Valley territory? It kinda defeats the purpose.

As for fanservice itself, I am firmly against the 'layer of body paint pretending to be clothes' trend that seems to permeate everything nowadays.
I dunno, maybe I am being a prude, but I prefer to watch my porn separately from things I watch or play for fun. Considering what I saw of marketing and art design over the years and continue seeing now, that is apparently an unpopular idea.
I'm just not seeing why anyone would do that. 'Sex sells'? Eh, if your creation took off in the masses, all that pornification is gonna fill all those h-doujinshi, fanart, fan games, flash movies, cosplay, etc, etc on its own even if the amount of sex appeal in the original work was tending to zero. And if it doesn't , then you ain't gonna find any Rule 34 material on it regardless of how much fetish fuel you pumped it with.
I suppose I am grumbling for the sake of grumbling. Really, I should be happy that Metroid doesn't have any loli appeal going in it yet.
