It's only text.There's not really editing to it, don't ask me though I don't even know how to put text down.
I don't understand how you claim the current one isn't "nice" looking. To me, yours is exactly the same as mine with worse colors, no shadow, and no overall design.Honestly, even though this is your "first attempt", you shouldn't really criticize the current one if you can't make one that is better, even after it's identical to mine.
