@JackMusic - Personally i'm a big fan of Mozart and Ravel. I'm not a HUGE fan of piano composition but I certainly recognize Chopin's genius.
The problem I have with excessively long melodies (which I actually write by default) is that they can end up sounding like "songs" and sound best in short forms (which I also write by default). Tchaikovsky was actually good at making those sound good but they ended up sounding like simple ditties compared to the works of Brahms and others who were able to compartmentalize the melodies for further development.
But the thing with writing on demand is that sometimes my client's tastes do not necessarily intersect with my own. This was the 6th revision in what was a pretty long and painful process, and the budget is what you might expect of a new startup studio without grants or other funding, so at one point I decided to just cut my losses and give them what they wanted. I might be having a bit of work in July where I can actually flex my mind a little more.

These are probably closer to my personal style. (I actually really really dislike writing melodies that are essentially a bunch of whole notes lumped together)
