The image is very nice, so let's play a bit. I am using two font sizes because we do not really know what is the size or the extension of the text.
The image a bit dark, it is at dusk, so let's use a white color. It does not matter that the text is perfect. You can read it.
But we can add extra contrast using a subtle gradient. It does not need to be black. I extended it a bit to the right so you can see it.
But we can make "local contrast" by using an outline.
This outline can be harsh as the previous one or soft.
Or you can drop a shadow, to increase this local contrast a bit.
You can inverse the colors to a light glow... But probably in this case does not work as nice as the previous.
You can also add a semi-transparent block behind the text.
But all depends on the size of the text, if it is big enough you can even make it transparent. The bigger the text the less contrast you need.
You can also just leave the image alone...
Now go and play with it. This was fun, enjoy your experimentation.
