Adding one pixel to make room for descenders on the text would help readability a lot. You could decrease the size of the ascenders by 1 if you're short on space, you don't need such long ascenders, and the dots on i and j could be removed safely.
Other than that, that text is quite legible for that size, despite some letters being identical!
I feel like the sky gradient should be moved up or down by a few pixels. Currently the colour bands tangent with the ground and poles on the building.
Thanks for the feedback! It's my first pixel art drawing and I'm hoping to do a lot better in the future :)
