It's not the monster in the vents they have to worry about. It's Samus!

I like her sneakers.

Sneaky sneaky.

I like the idea of a powered down Samus sneaking through some vents, and I think you really captured her expression and hair style to convey a "Samus attitude"
The gun I can over look as a weapon of providence in matching her usual gear, but the shoes look cool, are nice kicks, but are confusing within her cannon.
I don't know why she would have a boob window, it dose not suit her character very well.
I suspect you may have had trouble showing that it was two breast the window is a simple way to convey they are both there, but it's just a little jarring compared to how I think of samus.
Over all it's very good and kinda a funny take on her contortion abilities, but I feel you could have pushed yourself a little more.
Thanks for making this.

When charging head first into a hostile horde of extraterrestrial creatures is not practical, the route taken by Solid Snake is a possible alternative…
