Just little things may help, try one model,one background and one look per image for stronger port. Watch the models hands to make sure they are the way you want them. Try not to crop at the elbow, halfway to the shoulder is a better look. Personally, like to see you with/buy/make a bigger catch light,,, looks a little small for every shot, sometimes you want small and sometimes bigger, depending on what you want to do. Ya looks awesome,, look forward to seeing more.
I looked at your website.
You have the work/images to make a very strong port here or anywhere... I am sure it would benefit you and others to see your best work... Personally and professionally your strongest work is not here and it is very GORGEOUS work....
The new ones all seem strong in comparison with the rest of your portfolio, but in terms of offering something new, this one:
really shines as emphasizing the fashion, near formal look while still capturing the essence of the model. The black and whites in general, with their crisp detail and near infared vibrance, also caught my eye.
