Since you have to rec. an electrician for the neutrals just recommend also that they evaluate the whole installation. I would note in the report that the two 100 amp circuits could each be within limits but the total of the two could exceed the new panel rating and the service rating.
was the service entrance conductors 100 amp also?

It looks like the top two breakers are the main breaker. The SEC are visible as they go into those breakers.
There is one 100 amp circuit which feeds out to presumably the old panel.
A bonding strap is visable.
I don't see anything wrong with this portion of the system.

Looks to me like on the panel schedule the 100A middle ( top) set is the main breaker and it powers the buss and the 100A lower ( bottom ) is the disconnect main for the sub-panel located remotely…We will assume the 4 wires going UP feeds the sub-panel in the house some where.
Unless I am missing something this panel is rated at 125A and the main is 100A so it is within its rating...the main OCPD is rated at 100A as listed...and the main disconnect breaker for the sub-panel is rated at 100A...
About all I can see from this.....the ground looks good.....joined together at the first point of connection and separated from that point by evidence of the while insulated conductor...did you make sure this was the case in the remote sub-panel location.

100 amp back-fed main - no problem there (125 amp max).
The panel is clearly marked for a maximum of 90 amps at any branch circuit.
With that and the bonded G & N at load side panels, corrections are needed.

Hi to all
Jeff "clearly marked"??? what the hell are using for a monitor? I had to blow this right up to see that

Good catch Jeff but it also brings up a question.
The label says "Branch Breakers"
The problem is there are no 'branch breakers' in the panel.
The only breakers in that panel are the service disconnect and a feeder breaker.
I really do not know the answer here, most panels I see will say something like "No more than 100 amps of breaker per pole position" or something along those lines.
I have never heard the term "Branch Breaker"
I will be asking around for some more opinions.

Here is how I normally see it, this is from a Challenger Panel in my house.

That is a branch feeder breaker. It is a feeder breaker installed in a branch position.
My question is, if the main has contacts good enough for 100A - 125A then they must be made different?

Interesting.
Can you show me anywhere in the NEC it mentions a "branch feeder"?
I thought not. 
The only answer I can come up with that will work with NEC definitions is the feeder starts at the load terminals of the breaker.

Firstly, I think their is not a branch issue here…the service is set up as a main breaker and main disconnect setup within the same enclosure. As for the branch I would determine it was for use with running ancel. issues like feeding a lets say AC unit from this location…then the branch would have a max issue…glad eveyones eyes are better than mine…lol…My screen is only a 15"…I really need to invest in a bigger one…lol
I do not see a real issue with this installation....the bonding seems correct to me as it is the first point of connection and the main location...beyond this point the seperation is needed....anyway call me quirky but I do not have a issue with this panel......but again might be one of those things you have to see up close to know...lol...but I do not call the feeding of the sub-panel a branch and not a violation of this panel in my opinion.
The branch would come into effect if anything else is added to this panel to service something directly from this panel.
Regardless......we got some GREAT eyes on here.....sad to say mine are not as great...lol
