Feedback appreciated, -ATF Delete the layer called "Background", it should be the very bottom layer in your pallet. You have to right click and select delete to delete it. Once you do that you should see a white and gray checkered background. That's how you know it is transparent. In order to save it being transparent go to file>save for web>and choose a gif or png and click save.
Ok, here is my entry: No background/transparent background as asked. I can do changes. I'll remove the watermark near the "+" if you buy it. Feedback appreciated. Best Regards
