If you look at a lot of heavy duty trailers, the tongue rails are set up like this. It reduces bending stress a lot, especially at the welds, since the tongue-weight-bias has a ton of leverage and bounces against the tongue.
Everything else looks pretty hefty compared to most manufactured trailers around 10k lbs though. You're probably fine. Just thought I'd throw that out there.
Making the members taller at high leverage concentrations will be the most efficient for weight and strength. You might want to add vertical plane between the end of the tongue and just behind the front of the deck. Doesn't have to be very thick, the height is what counts more than anything. I can't really tell how tall the beams you're using are though. They look quite a bit taller than what you'd normally see, so again you might be just fine. Just throwing out ideas
I would say the one benefit to 3 axles would be if you get a flat (or two). It's a lot easier to chain a hub up off the ground if you can put a tire in front of and behind it...I've actually lost both spares on more than one occasion
. Two axles is way more maneuverable and easier to load properly though. Not to mention you spend less on tires. I personally would only do a two axle.
Are you going to run a deck or just leave it open framework?
