No don't worry about it! Emblems are merely little trophies that demonstrate what kind of impact you as a member have on the forums. In your case, I felt it appropriate to issue an emblem that commemorates the work you've done in A&D; specifically your pixel art.
And while emblems themselves don't actually do anything, they are a fun little way of letting other members know that you've done something extraordinary for the pixel art community in A&D. Which is true! Your fakemon gallery is stunning and very deserving of the emblem!
So don't thank me, although you are very welcome! It's my job as a mod to take notice of members who stand out from the crowd. :)
