Great job. I love the paint. Everyone had great tips. Maybe challenge yourself monthly to create a new signature so you can get used to creating them and in no time you'll be a siggy pro!
I haven't read the replies, but sometimes I will convert a cluster from one of my pages into a signature. If I'm starting from scratch, I start with my name in my desired font or alpha and then "decorate" it. What you have looks great! My only suggestion would be to minimize the paint splatter or blend it out so it doesn't overlap the edge (but that's just a personal preference).
I love to make a little "scene" with my siggies. I typically use this formula: font or alpha for name sprinkle/scatter/paint word strip or word art any elements that I think will work for my "scene" Sometimes I'll add a paper bit or two, or a piece of washi tape. I try to keep them simple because they're so small. But in all honesty, I love looking at everyone else's siggies for inspiration. There are so many amazing ones in the forum that they always amaze me. Liz's templates do make it easy to start - you can add/subtract as you please. Some times a little starting point is the jumping off point you need. I hope this helps!!
