Tom,
Very nice job. I like the color. Like the real thing, it seems to change from one photo to the next. Which did you use?The rusting on the exhausts is very nicley done as well.
It is true that Accurate Armour instructions are not the easiest, but the photos do help with the parts placement.
I'd like to offer a few suggestions on placement. Bear in mind these are only my observations based upon photographs I've seen-individual mileage may vary:
The fuel can on the right front fender needs to be turned 90 degrees counterclockwise. It would be difficult to get it into its holder the way it is now. The tow pintles seem to be one backward. They can be mounted that way, but would not be useful in that position. Lastly, I'm not certain about that right front fire extinguisher on the stowage bin.
As for the tracks, I know this is your first resin kit, so they can be tricky at first. If possible, you can remove the side armour plates, and heat the track with a blow dryer. It will become very pliable, but be careful, so will everything else. You may even want to remove the front section and heat it away from the rest of the tank. I wouldn't worry about trying to mate it up to the top run-it's hidden, and with resin models, I don't even add the top run at all if there are side skirts. Besides a gentleman doesn't look under skirts.

Your markings seem right, without digging up a bunch of references. The registration number appeared in many different places over the years. For the era yours represents, you might take the one off of the rear hull, and place it underneath the left front stowage bin on the turret. My eyes fail me, so I can't tell what the three markings are on the right side skirts, but the chevron placement is fine.
All in all, that's a tremendous effort for a first resin model.
