Hi Alan.
Haven't seen your work before - thanks for this series.
Anna, although pretty, would have come up nicer with some styling - makeup in particular, to smooth her skin and take away the sheen so commonly projected with people with darker skin.
Her pose seems a little unnatural, but a gallant attempt at looking sultry
Lighting's OK, although not extraordinary. The setting doesn't do much to bring out the subject. Some distance between her and the wall would really have helped take away the slightly distracting background - looks like you had the space to do so.
But overall, decent portraits and with some pre- and post-production tweaking and more flattering lighting would be definite keepers.
