In the statement of the problem, I detect no trace of the problem, therefore I offer no solutions. The length and complexity of each of these four sentences is within the window of what I consider tasteful. One could write sentences more complex, or infinitely complex, but that's mostly to be avoided, in my opinion. Complex sentences, unless written with great care and subtlety, tend to call attention to themselves and to the writer, and that's a failure. If I'm distracted thinking about how the writer is showing off, I'm no longer thinking about what I'm reading. Meanwhile, strategically sprinkling in the occasional short simple sentence is a fine way to achieve various desired effects, including variety of cadence. And of course there have been famous and successful writers of English who have gone farther than that, to the point of choppiness - most notably Ernest Hemingway. "I had no feeling for him. He did not seem to have anything to do with me. I felt no feeling of fatherhood." To me that also starts to draw attention to itself, but at least he can't be accused of being bombastic or grandiose.
