Help Kraftwerk create a dream journal sig pic!

Uh.. Hi artist corner. I'm suprised I didn't notice you earlier. Anyways: I'm here because I need some help/suggestions creating a signature picture for my dream journal. What size should it be? What should the color scheme be? What font should I use? I'll post my attempts here! Thanks!

You could use the tutorial linked in my sig for a general guideline, just skip the bit about dream goals and make it just say "Kraftwerk's Dream Journal" in bigger text.
