Happen by my little world
And by chance you'll see me standing
Shoulders back confidence
Doing all of what they are demanding

If you should peek outside my life
You might catch me on a good day
Smiling contintley at the clock
Without a single complaint

It's fun to imagine the stranger
Who happens by my world
Who tells their friends and family
About this head strong little girl

How I look so self assured
With my posture-perfect stride
Being everything to everyone
And pushing me off to the side

Look once at me and notice
How my world is free from harm
Look twice and then you'll see
The perfection marking up my arms

I really like this. Striking. Not sure about the second line in the last line, maybe a little too direct? That is only my opinion I guess Good writing! Also, just an afterthought, but maybe do something with the title; "on my arms" made me instantly guess what it was about, maybe that is your aim. I prefer titles that make me think, what could that be about. Making me more likely to read it.

Sunshine and dream clouds,
