Don't wear that tie. Shirt collar should lay underneath the lapels. Pants need to be hemmed, since they have a small leg opening, minimize the break. This will help avoid them from looking like stacks on jeans. Hold your arms forward a bit to help with the sleeve pitch. Wear the back of the trousers higher so the fabric doesn't wrinkle.
