I'm afraid the size of it is quite impossible to resize to our standard (450x150). As your image is more of a square than a rectangle, if you try to resize it, you will only be able to fit part of the original image or it'll end up being really small. If you like, you can request a new one where someone can try to recreate the original in a size that will fit our standards? ^^ (Using the same image & text, etc)
