Since that is a small box, the house amp should be vertical and NOT horizontal as it is. There sould be a ground block that feeds the house amp. You could probably get away with it being horizontal, if the input wasn't RG7 or 11 (can't tell exactly which it is from the pic) because you have to remove the amp in order to service the input connector.
The service loops look good, except you neglected to have an input service loop and another service loop is needed for the line directly under the input.
As for having the house amp in the box goes, that is no problem. Those house amps are weather proof. You just should have installed a ground block and grounded it, and bonded the house amp.
