Your port looks to me, and I'm no expert, like the upper end of the make-up spectrum. Some of it is so exceptional that I'm not sure where make-up stops and photoshop begins.
As above, you have no pics of "ordinary" make-up which is fine if you are not interested in bridal, glamour etc.
If you can carve yourself a niche concentrating on this stylised, high fashion look, you will be at the mercy of trends but might also get really lovely work as a more specialised make-up artist. Probably not here though. I'm talking about the big wide world.
That's why I suggested before/after shots
Here's a good article about before/after makeup (although it's with pornstars, it's safe to view) that illustrates the sort of looks I suspect most photographers are after (contouring, smokey eyes etc.)
Thanks for the advice, I will definitely get some before/after shots next time I have a glamour/fashion shoot ?? I can understand why it would be good to see the quality of before and after. The only thing that's a bit of a black hole though is you don't know whether the 2nd image could have been professionally edited (therefore not all before and afters would be as realistic as you think) but going to get them done anyway x
