I like entry #11 and #12, but need webb to be aligned left like our website has it because we have physical signs and other signage like that already. Maybe try to combine entry 11 and 12 and then also make the blue squares look more like actual orthodontic brackets.
Ok, really like 28,29. However, I'd still like the brackets to look more realistic, shiny, 3-dimensional. Check out opalorthodontics.com. Those are 3D renderings of brackets.
