Looking good Trooper
At Garrison level you only get approved (basic) and the higher levels (EIB and Centurion) are done here at the Detachment.
Apart from already beeing mentioned for L3 I would guess your belt need to come up a tad but you’ll never know, I would have requested it during my time as a D.O anyway, here’s a reference: (I was a picky one so you can just wait to see what the current ones say at your EIB)
Regarding the shoulder bells, here's a look at how an original bell looks side by side with a not so accurate one. The original (left) is trimmed with a curve hence beeing more suited for closing eventual gaps to the chestplate, not sure If you have enough left to trim yours but it might help others
