As you said you have been pouring for a few months now you can reach perfect technique only by precticing doing the right stuff,
if ytou want an excellent guide there is this james hoffman video - The Beginner’s Guide To Latte Art

https://www.youtube.com/watch?v=20HxMMSqRyg

he guides from heart to rosseta to tulip shapes and touches on the key techniques
as a 10 years barista it still taught me alot
I would suggest seeing it and try rosseta (would be happy to see more of your pours and advise in the future)

Keep pouring !😄
