Hello - Thanks for your submission.I like the idea of using a circular element and then a pictorial image within. Can you make the circular element more like the letter "c" (by removing the "arm" that stretches from the right side of the circle towards the middle). Also, Can you make the building silhouette's bigger? Can you incorporate an abstract crane (maybe a gray or green one)?
Also, our company name is "Costello" not "Costelo"
