It it hard to tell from 2D photographs, but if there are points where the copper tubing touches or gets close to another pipe or other hard objects, put a little foam rubber or something (maybe even a few layers of duct tape) in between to prevent them from rubbing through.

Also, pull vacuum from both sides. That's the proper way to do it. Then put in a holding charge (a few PSI of nitrogen, up to 150 PSI or so if you're doing a pressure test) until you're ready to finish the triple vacuum and tune it. You can also finish the triple vacuum outright and then put in 50 PSI of refrigerant for a holding charge, then add more when you're ready to tune it.
