Looks like a good photo! Can you save it again in Hi-resolution? Make sure all your boxes are checked before hitting enter.

Without a High-Res, we really can't see the image properly, what we see here is a down sampled version of what you uploaded, this is why it's important to tick Also save full resolution image. You can still do this.
