Welcome to the forum!
It's pretty dark... I wonder what you metered off of? For sunsets you can get nice colour by metering off the area of sky
beside the sun,
without including the sun in the picture. Then recompose.
The cloud shapes are interesting... putting the sun right in the middle might be considered a composition no-no. There seems to be not quite "enough" in this picture...
...but then if I was on a beach in the Seychelles I'd thumb my nose at what
anyone thought
Keep shooting & have fun.
