Is My Russian Correct... ?

I made a gift for my friend who is going back to Russia soon.
(Let's not worry about what the gift is) But on the box I put her gift in, I was going to attach a tag to it with a note on the front and back.
This is what I plan to write on the tag.

On the front side:
"Это для тебя"..
This is for you. Correct?

And on the back side:
"Спасибо Алина! Да, Я сказал спасибо!
Хаха :]
Я Люблю Тебя!"
Thank-you Alina! Yes, I said thank-you!
Haha :]
I Love You!". Correct?



If I made any mistakes please feel free to correct me!
Thank you very much!

Well done. :)
But generally Russians do not start words with capital letters, unless they are names, and you missed a comma. So I suggest some minor corrections:

"Это для тебя.
Спасибо, Алина! Да, я сказал спасибо!
Ха-ха :]
Я ЛЮБЛЮ ТЕБЯ!"

Thanks for the contructive criticism!
I'll be sure to correct my capitalization and remember to do so when Im writing and typing. :]

Спасибо! "Xa-xa" :P
