I would second the recommendation of considering the the 35mm f/1.4 for another lens. I love my copy and it's on my camera more often than any other lens I own. With the Fuji discounts, it can get close to your price range new, but I'm sure there are a lot of used copies in great condition out there from people switching to the f/2 model. I think both versions are great lenses, but I personally prefer the f/1.4.
All the lenses in your list are very good (when used with the latest body and lens firmware), but looking at your excellent photos I noticed that the portrait shots tend to be head and shoulders or waist up, rather than tbe longer distance full body 'fashion photoshoot' style. Your shots of the Enfield Bullet are also quite close up. This makes me think tbat either of the 35mm lenses would be better for you than the 60mm. And if you do want a head to toe portrait with an out of focus background, then your 55-200 at 55mm and wide open will work well enough.
There's a lot of debate about which is the best 35mm Fuji lens, but as your X-E2 is not weather resistant, and as wide aperture / narrow depth of field is important to you, then go for the 35mm f1.4.
You will not be disappointed with this lens, and it adds a look to portraits that the 18-55 and 55-200 cannot match.
tuck4x4 got a reaction from frankinfuji in 35 f2, 35 f1.4 or 60 f2.4 for portraiture/general
