The price you ask for indicates that it's a double side board? Is that the case? If not, the grounding needs to be redone.

First thing, that comes to my mind: soldering LME49600 to this big ground plane will be pain in the ***... Just saying...
Also, opc made great 49600 application and making more of them slightly different is kind of pointless, unless it is practice for you, then go ahead, I don't want to discourage you

the lme49600 is mounted inversely to facilitate the mounting of small heat sinks

That's clever !!

and saves having to preheat the PCB to solder the heatsink pad to the underlying copper trace.

It's more than clever, you are brilliant.

How easy is it to bend the Buffer leadouts to face onto the reversed pads?
