Greetings @Luiseach 
Maybe this is just me, but I don’t think there is a skill cap or level lock when it comes to witchcraft! While there are certainly some aspects of the Craft that are generally labeled as “advanced” (things like lucid dreaming and astral travel come to mind), it is definitely true that some people have a natural gift for these things- some do them naturally, even before they identify as magick-users! I don’t think anyone should discourage someone from pursuing an aspect of magick due to how long they’ve been practicing.
(Not to mention that deity worship is extremely common- considering both ancient history and modern-day religions, I’d say the majority of the general population worships/worshipped one or many gods. I consider deity worship to be a very beginner-friendly practice!)
I say do whatever calls to you, pursue whatever interests you- this is your practice and you get to lay the rules 
While there is a lot to be said about following your natural intuition, I am a scholar at heart and I always recommend research (sorry from me too haha) to back up what you’ve discovered intuitively or through experience.
If you think that the Morrigan has possibly been trying to connect with you, that’s wonderful and worth pursuing more! The Morrigan is a fascinating deity and you’re in luck- She has been a hot topic around here recently!
I’d recommend taking a peek at some of the following discussions to learn more about Her and read the experiences of those who work with Her 
→ The Morrigan: Celtic Goddess
→ Has anyone else learned about the Morrigan?
→ A prayer or chant to Morrigan
In case it turns out that Morrigan is not the deity for you, then Hekate (another popular Goddess) is also associated with crows/ravens- perhaps look into Her as well? Just a suggestion- wishing you all the best with your search to connect with a deity! 
Blessed be!
