Not sure how many will catch this or if it was even intended, but I like the hair color vs. clothing matches you have here. A bit dark/subdued in my opinion and maybe even a tighter crop would put more emphasis on them, rather that a lot of background.
alright studio pic. could use some cropping. Drop the studio lights down to about 3 feet or so to capture the life in their eyes. A little hair light would give this pic a great glow.
