Nice work, Raymond.
Of them all, I think my favourite would be 4... really nice range of shades and composition.
Can I ask what you did to post process these? They seem to have a bit of desaturation / faux cross-processing going on?
One recommendation I would have would be to build a final sharpen into your processing workflow (after resizing to final size/resolution). For me, these are all lacking a bit in definition - particularly around the eyes.
