Hi enrique,
Because the piano is left on stage where the maintenance people put it (the auditorium being empty), the tail is facing the audience in the picture. But when you made your recording, the piano might have been in some other position. It's probably moved around depending on needs and then moved again to get it out of the way.
Basically, you have a portable recorder with on-board stereo mics in XY configuration with the mics at a 90+ degree angle to one another. Unlike A-B configuration where you have two standalone parallel mics pointed at the piano (probably 8 to 10 feet in front of the curve of the piano's rim for a concert grand), with XY you need to be closer in to the piano. I would guess about 5 or 6 feet from the curve. To fine tune it, do this: The mics are exposed in the unit, so sight long one mic, making sure that the mic is not pointing beyond the keyboard cheeks, and when you sight along the other mic, that it isn't pointing past the tail of the piano. In other words, using XY you don't want to "overshoot" the length of piano. The keyboard and tail are the outter limits. If you're overshooting, move a foot or two closer to the piano.
Ideally you'd want to elevate the recorder perhaps up 6 feet or so. A six foot step ladder could be used whereby you could lay the unit on the top of a six foot ladder, or a lower step if more appropriate. Even a folding chair or table could be used to gain some height. But that stage is neat and devoid of anything but the piano. You might look behind the stage doors to the left and right wing of the stage. If they're unlocked, have a look there to see if there might be something useful that you could momentarily borrow to gain some height for the recorder.
I would not advise placing the unit under the piano. It's true that sound escapes not only over the rim and as reflected outward by the raised lid. It's also true that when the soundboard is reverberating that sound drops downward from the underside of the soundboard. But I've heard a few pianists trying the under-the-piano placement, and the results were not very good. Placement inside of the piano is best for jazz and pops, but not classical music--there is too much of a percussive sound quality along with other mechanical sounds present inside the piano. You don't want hammer-on-string sound in the making. Rather, you want a finished, blended and refined sound. That means staying outside of the piano.
Another possibility is closing the lid and placing the recorder centered on top of the lid (either fully closed or with the front articulating part of the lid laid back on the rest of the lid). Some surprisingly good results have come from that positioning. It's not ideal, but it can be a workable compromise.
In an empty, "live", auditorium, placing the unit out in the seats will give you a distant, reverberating sound--far from ideal. That's what you have now. I hope that the suggestions above will be helpful.
The best approach to microphone placement is experimentation, experimentation and experimentation.
