The makeup is also quite distracting for me, it really draws my eyes to your eyes which highlights the "rabbit in a headlights" type of look - which is never good. Plus the head shots are far too skin smoothed. Don't get me wrong, love a bit of smoothing but the retouchers has obliterated your beautiful skin.
I do like your work with Rob though and I don't think these match up in comparison to be honest. I know its tricky being up there and there is a serious lack of photographers to select from so it might be worth heading down to Edinburgh/Glasgow to see what their photographers have to offer.
Theres a wonderful photographer/makeup artist team based in Dundee who I highly recommend. They really do bring out the best in people, I've shot with lots of people but after leaving their studio I have actually felt like my body radiates confidence and their regular clients tend to agree.
