Actually, I like you added the double size (just as on the other ones you made earlier) because it gives a nice stylish feel! Also, the black background fits to it!
As long as you keep making cool stuff, I would not worry too much about your boredom ;)
It may seems simple, but I found it very interesting. Even the palette, very unique. Love to see more.
Could we get a Transparent background, and you don't have to include a double size.
Haha, I like the style.
