You over trimmed AB plate and the reason your Kidney plate and notch doesn't line up, AB shouldn't be trimmed beyond red line, by removing that specific angled section on your AB plate you reduced the height of your AB and doesn't match the height of the Kidney plate, also your shoulder straps are at wrong angle, there should be much more gap between the two, basically be more straight going across the shoulders, your biceps are way too big they should be tight fitting as most as possible.
