Sandpoint Homebrew battle map

[Ravenbow]

I created a map for use in a modified Goblin attack on a cathedral during its opening celebration ala RotRL. Am I allowed to post it here or post a link to my blog where it is posted? It is NOT Sandpoint but was inspired by Sandpoint. I wanted to make that very clear for copyright reasons. I just did not know where to ask.

It's my understanding that you can post anything that doesn't have stuff cut and pasted from Paizo images, including redrawn or traced maps.
