I'm a fan of colour. I generally choose the colours before I choose what to paint. These colours make me happy when I look at them.
The choice of title of this artwork is twofold.
Firstly, in this painting I see groups of families walking to a better life.
Secondly, it was painted during a time when I myself was making changes to my life and becoming someone else.
The dictionary definition may help to give you a better understanding of what I'm trying to say here.
trans·mi·grat·ing.
to move or pass from one place to another.
to migrate from one country to another in order to settle there
(of the soul) to be reborn after death in another body.
