Good job shooting RAW and editing in Lightroom.
Consumer monitors are notoriously poorly calibrated out of the box and often too bright. If you end up getting more into photography, you might consider a monitor calibration device. I use Spyder4. It is a usb device which hangs over the front of the monitor, analyzes the display and then adjusts the monitor profile the operating system uses for the display.
I have 3 displays, and with default settings one is somewhat blue, one is a bit pink, and the other a bit green. After calibration, they are not identical, but definitely improved and much more in the ballpark of each other. During the calibration process, the software allows one to switch back and forth between calibrated and uncalibrated views so one can see the difference that is being made. The modified monitor profile is loaded on boot from then on. Recalibration is recommended every couple months, as monitors tend to drift over time.
While there is no guarantee that someone seeing your images will be using a properly calibrated screen, you can be confident your images were produced with decent brightness and color levels.
