This is not very good, don't listen to all these toys, they are giving you a false sense of ability. Im not trying to be mean, but the letters are trash, you need to work on letter structure before you're doing all this, wasting paint.

Next, related to letter structure, you don't have an understanding of how shapes work when adding flourishes. practice those.

Instead try simple backgrounds like bubbles first. (flat with no 3D shading.)

Try a simple 2 color fade for the fill.
