I would go for a different style, maybe a saddle bridge too... it's usually more comfortable. Have a look at the Oliver Peoples Brisdon or the Moscot Hitsik (maybe the arms are going to be short, though...). The Hitsik is like a rounder, better looking New Wayfarer.
The 2 glasses you showed have those "elbows" that stick out, and that makes them less sporty and maybe like a "heavier" look...
Another suggestion of style, but this is assuming you like big glasses, have a look at a Cazal metal frame. See if you like it.
Glasses are an important purchase if you are going to wear them all the time, so it is worth to shop around and try many options. And glasses need to be tried... it's impossible to have an accurate idea of how a certain model would look on you without trying it first.
Finally, if you are considering an acetate frame, a lighter frame colour will take off "weight" off thick acetate, and you will be able to see the metal core inside of the arms, which looks cool. So if you went for the Lemtosh, try to take advantage of the multiple options that model offers in terms of acetate colour, from translucent, to shades of semi translucent acetate, to black.
Another brand that looks either great or terrible is Cutler & Gross. Unfortunately, they are too much acetate for me, but on some people those glasses look awesome.
Focusing on the style in your pictures, you may also consider some of the rounder models by Oliver Peoples, like the Sheldrake, which is one of the classics...
