Beautiful shots, Surapon!
Love the one with the little girl on the bridge Surapon! the back light portraits are great too! can be tricky to get right.
I have the lastolite ezybox 24" thanks to suggestions by neuro, RC, and some others. So I can personally recommend it now. It's fairly portable and offers great lighting for single and double portraits. And i wanted something of good quality. Not the cheapest though.
