Your's image it's way better than mine,yesterday i made the logo to,to do this i started the image over again,i resize and grayscale it this time only with infant view because photoshop is making bugs at the pixels,then i opened the image with the paint,i expanded the up side,i pested the sprites again and the logo,and at the end i puted a gamefreak styled aerial emerald with photoshop.
However,send message to anonyboy that you made the banner,the mountains are better from the sea,i just puted the sea because in emerald groudon,kyogre and raqguaza battles in the sea of sootopolis,and because i though that kyogre can be only in the sea.
Close message:The line at the arm of groudon in the the new(your's) banner is not red :).
Great job,i say it seriously!
