Just wanted to share that there are some effects in the image that would not work in the format the logos must be saved. logos are best save in vector formats because they are not dependent on the size or dots per inch of the image. it can be resized to accommodate large format printing without having to worry about losing its sharpness. the only trade off is vector formats are sharp and has limited capability to simulate realistic effects in the image like diffused shadow, soft glows, basically 3d effect.

I just wanted to share this because i noticed your image is almost realistic feel. To achieve this you need to "do it in 3d" but the output files are not print suitable unless you have the 3d software and resave the image into the size you need.
