As free as a little bird

Whilst Living in France continues I increasingly feel as if I am achieving more and more to be

 as free as a bird... 

I recognise that I am only imprisoned in my own cage when I forget how to sing and dance or when sadness creeps over me like a dark cloud. 
Yet, when the sky is blue and the sun is warm my varying persona emerge as one and then I love to fly free ... in fantasy, in reality and I become happy.
Is that poetic nonsense or an artistic creative literary style? 

I would have preferred  'l'hirondelle' but this chubby chappy is such fun ...

he will look down upon me and I will always look up to my little bird!
