So the crimped 'lugs' were just heat shrinked, and wrapped with tape? I don't see a shot of what you did with the lugs after they were crimped...
Having done battery relocating before, I used insulated firewall connections from Moroso to allow the cables to penetrate the firewall

I'm also no fan of 'crimp only' connections. Eventually, resistance will build up at this juncture. As much as the owner may have the desire to return the vehicle back to stock, I'd have tried to convince him/her that they could always just purchase the OEM 'lugged' stock cable. Especially with full battery power running through these cables. I like to tin the cable first, as well as fill the lug with silver solder, then immerse the cable into the lug before the solder cools. You can always add heat and re-seat the cable if you didn't get the desired depth. I
then crimp the lug in a vise for safety/overkill.

To ensure you haven't disturbed the integrity of the heat shrink, it is advisable to use a heat gun as opposed to a flame source on the heat shrink as well.

A rated cutoff switch is a good idea as well, as I'm sure no one here would want to see their pride and joy go down in flames. They can be hidden or positioned as necessary if you are regulated by a sanctioning body. On one of my fox bodied cars I hid it

In addition, it isn't a bad idea to use a circuit breaker when relocating either. I have successfully used a 200 amp fuse instead of a CB (just remember to keep a spare in the glovebox , JIC) to avoid a meltdown in case of an accident that causes a short in the cable somewhere

Not a bad time to upgrade to a more powerful battery either. I've used Optima's in the past with great success. Nice thing about their cell type is that you don't have to be concerned with venting like you do a stock battery ( I saw no mention of venting in this writeup either).
