Once again a lovely piece of art and like all your other art it has been drawn with such perfection and to such detail that it really is magnificent.
The only thing I dislike about the image, is the text inserted into it: "G's night club", "Live music", "Cocktails" etc. They simply spoil the image, but then again don't get me wrong about the whole art as it is terrific but the text does seem to spoil a perfect view of the image. [A critique is for others to point out your mistakes and to spot your creativity so that the next time you'll work out better art]
I love to have spotted the "Big Ben" in this image, even if you didn't create it as Big Ben. Also once again, the azure illumination from below the buildings looks terrific and adds a lot of depth to the image, making it more appealing and making the sub conscious tell us to view the image closely. The aligning or symmetry as I should call it, of the buildings is to praise. The gradients of ash gray used with the shadowy appearance somewhat magnify the image.
Once again, a job well done. You do not fail to impress me, keep going forward and hoping to see more great works of art from you in the near future.
