its definitely a nice improvement. it flies pretty well and i was able to take off and land easily enough. im sure with practice and fine tuning your designs will continue to get better.
as far as suggestions, a good thing to keep in mind is that the flight characteristics of the aircraft will change as it burns fuel, especially since your aircraft can carry over its own weight in fuel. while its maybe somewhat sluggish at full capacity, its much snappier once a lot of the fuel is gone. otherwise, all it really needs is some stability improvements and it should be really solid.
Edit: maybe some airbrakes its not a requirement
