I think the star is overwhelmingly bright. A large portion of the image is covered in glare, which I think is a bit too much. Lowering the glare would allow the focal point to be centered somewhere at the building the camera is facing at (which you can use the side buildings and walkways to form a leading line that draws the viewer towards the centre where there is a building of significance). At the moment, the entire image is overwhelmed by light.
I am interested in seeing where this artwork will go, and what it will develop into.
Although I agree with this, it’s a large part of why I think the image is so effective – I literally squinted at the glare when I first looked at it!
