Hey Sebastian, What you did, it's amazing. I'm Thai. I was born and grow up in Thailand. I can't say anything. Well done!! Please keep going and find your way with Thai song. We are all open for new thing and support you.
If you can say this alphabet correctly, then you are half way there ( ง ). Another alphabet is ( ป ). These 2 alphabets are the most difficult for westerners to pronounce them, but once they have mastered these, they will not have any issue learning Thai. Awesome job, Sabastian!
