I do agree that at this point, your style itself doesn't get much better, but that's exactly why you should be at the point where ripping traits and styles off will add than subtract.

But for now, the obvious things.
Round out your lines and practice more anatomy daily.
It uses a lot of paper, but yeaaah.
For something specific, I'd say your jaws. They sometimes have zero depth, so it gives the impression of them being literally sharp. You're improving from those what I see of those three though.

Make your shading and inking simpler.
A good "unlearning" to take from would be the simple no line styles of peachifruit (hard to find outside her fancomics since she deactivated her DA.) and Takehito Harada (Of Disgaea Fame)

As for bursting breasts, remember the pull in gravity and the natural slope a breast has.
Such as a squeezing expansion will warp the bottom half of the breasts towards the free area and then plop down when it breaks apart.

I have a good (though not translated) diagram off pixiv for the general idea.
Its just a matter of how much weight, fullness, and slope you want to put into it.
Personally I like teenager like fullness but with realistic slope.

Or if you don't mind having to learn a different pen style, which honestly shouldn't be much of a problem, investing in a Bamboo tablet would eliminate most of the secondary problems with trial and error.
