^ He got most of it. Try a smaller canvas size. Render is too overblended, like Cynical said and the BG. The BG is too busy and messy. Might be weird for me to say this but I think the whole thing needs a bit more depth, looks flat imo. Text...change the font, it doesn't fit with this style, the color and remove the stroke.
I suggest you read more signature tutorials and keep on experimenting with different outcomes. Keep trying!
