Getting creative during sunset (and a question)

Hello everyone!
Let me start with a sunset
I think it was the most beautiful moment of this week so far

And this is a photo from when I was chasing it, hoping to not miss the sun!

And look at this! I brought something with me today 😊

A little plastic vase where I did some drawings

This used to be a juice bottle

I wanted to put some color on it so that I can make it a unique vase

And

This is how it started

And some of my practice

Does it look like a swallow bird to you?

And now the question

I am thinking of painting a short wall. I have never done it before .. What are your suggestions? Where do I start? What will I need?

Thanks for visiting my post, hope you enjoy it a little bit!
