0.45x wide angle on 30mm help please...

[Rosh]

Some have you may have seen my thread about 30mm to be used on a holiday. In that post I stated that the big pitfall was needing a wider angle to get City Scape and Landscape images. I stated I used a wide angle 0.45x on the end and was unsure if it reduced IQ. Took some shots today. I zoomed into the 40km sign and could not see a difference. Please let me know your thoughts.

Easy: can't tell from this size. You will need to post links to something much larger.

I suspect that there is a bit of chromatic aberration in the brickwork and far left fence panel. Some 100% crops might be the go.
