I'll save the sarcasm, since you'll get plenty of that here.
Couple things to note, alot of your shirts look too big in the neck, size down to something that fits snuggly.
I think you may be tieing your ties too short, and thats the reason why the knots are soo huge.
Tie them at a length where the bottom of the tie is touching your belt buckle, and you'll find that the area of the tie your using to make the knot is the slimmer part, resulting in a smaller, better looking knot.
Also adjust the knots after you tie them, i often grab a portion of the knot and pull it tighter and its the difference between a loose, crappy looking knot, and a tight sharp looking knot.
You jackets look too big, have a tailor take your chest measurement, and see about buying some jackets that fit, i think it would be pretty expensive to have most of those altered to fit.
Props for actually making a reasonable attempt to look nice, which is more then can be said for 90% of the people out there, with exception to this forum.
I'm rarely surprised by the amount of sarcasm presented in a post like this, but its pretty disappointing, you guys should be looking to help, not Knock everyone.
