Letter.

I'm helping a friend make a video to thank a Korean group for coming to the US and I'd like to do my video in Korean, so here is what I plan on saying, I'd really appreciate corrections and maybe explanations on those corrections so I know why it was wrong and can make a better effort to correct myself in the future.

안녕하세요, Kaylan 입니다. (Hello, my name is Kaylan)
[I'd put my city name here] 왔어요(→ 에 와주셔서) 고맙습니다! (Thank you for coming to [my city's name here])
콘서튼(→ 콘서트) 뒤에 친구랑 저(→저는) 문신이(→문신을) 얻었어요...보는(→보이나요)? (After the concert my friends and I got tattoos...See?)
편지 읽었어요? (Did you read my letter?)
보고싶어요..(I miss you...)

[After this I want to say please come back to my city(I'd put my cities name), but I'm not sure how to say that.] ( → (cities name)로 돌아와요~ )

수고하세요! (Thank you for everything..or thank you for working hard).

한국이(→ 한국어) 잘 못해요, 미안해요. (My Korean is bad sorry.)

또봐요, 안녕!! (See you later, Bye!)


I'd really appreciate any help, it would mean the world to me to be able to accurately speak Korean in the video.
고맙습니다!

Most of them are good! Your Korean is good, Don't worry! ^^
