This is a good start. I would consider some editing if I where you.
The story lacks in detailed descriptions which is a key part of writing.
About the "* made it up thing," When it comes to writing, depending on the subject, making things up is sometimes a good thing,and sometimes bad. I'm guessing by 'steel- zinthanium' you mean some type of metal? I'd sugest changing that to a real element. And, adding a summary, not having a summary pushes people away, but it's also against the rules here, so I suggest you change that before someone reports you.
But other than that, the story is good.

Not bad, needs to be a bit more descriptive, but it's a good start.
