What kind of modeling are you looking to do?
There's
Fashion - Runways, Fashion shows
Commercial - TV, billboards, packaging
Promotional - Anything from trade shows and conventions to being hired to hand out free samples. Focuses less on your looks and being photographed and more on your ability to interact with people.
Glamour - Anything from calendars to swimsuit magazines
Male fashion models are usually 6' to 6' 2" tall and wear size 40 regular jacket. It really doesn't matter how tall or heavy a commercial model is.
You do this thing with your face when you're trying to look sexy for us. I don't know how your face looks when you're
not doing that but it gives your face an unattractive, bottom-heavy look to it. Bite the lip, look aloof, but don't give the "ANSWER THE QUESTION" stare. Try taking off the glasses, growing your hair out a little longer, shaping the eyebrows, a new look and call me in the morning.
There is a difference between toned muscles and too much. Fanatic bodybuilders seem to think rippling muscle mass that swallows your neck and makes you so big you can't reach across your chest looks good, but they're the only ones. Your legs look like a couple of hams on pencils. Weightlifting is not a proper hobby for a model, fencing would be great though.
You also have this habit of flexing so much you look like a tool. The key is subtlety; let people notice what looks good, don't force it on them. Why are you trying so hard?
The most ironic thing about this thread is that for someone that seems so concerned with worldly things like government, philosophy and economics to want to be in something so shallow and self-centered as modeling.
