Both work well.
At first I liked the fun of the ribbon border ... but then ...
I the simplicity of the red called to me. I guess I am the lone one on this thought!
Why? My conclusion was that your unicorn has a lot going on with the multi-colours,
and the ribbon border was competing, even pulling my eyes outwards to it.
Whereas, the plain red seemed calmer and let my eyes focus on the star ... your unicorn.
Unless you need size, I might even consider no border, instead using the red as a binding.
And too, would make the binding a wider than normal one, to give a nice frame around it.
