Too small of a space for guild crests?

[Solestro]

Hey there, I was just attempting to make a new guild crest, and it seems that it is a really small area to work with, In my opinion 16x16 is fairly difficult to create something more creative and that will stand out. I feel like maybe even doubling the size could give more people a chance to create what they want their guild crest to be and increase their creativity.
