Here's a thing I don't get to say that often - the contrast is too strong. The image is very hard to look at, you have both pure whites and almost pure blacks with almost nothing in between them to ease the eye from the first extreme to the other.
Here's what your values look like right now. The peak is what you have most of. Notice how far to the right (white) it is. (I'm aware that includes the BG)
Here's what they look like after I changed the image a bit in the brightness/contrast tab. Still favouring the right, but noticeably more to the centre.
And here's how the image itself looks now:
It's easier on the eye and the whites and blacks pop out more.
Less is more, mate! Hopefully I was helpful, I'll keep an eye out for the next update ;3
