introduction in Japanese

はじめましてぼくわkatherineです。よろしくおねがいします。

any good? :L

Hi katherine! Nice to meet you.

I'll tell you what I noticed.

はじめまして。私（わたし）はキャサリンです。宜しく（よろしく）お願い（お願い）します。

If you've already understood well about "私" and "僕（ぼく）", you can say "ぼくは" in stead of "私は" because of loving the word or any other reasons. But you shoul say "私は"　as "I" at the formal situation.

male 私は, 僕は, 俺（おれ）は

female 私は, あたしは

It's the best way to say "私" for both of male and female formally.

Af first you had better learn Japanese with the formal expressions or writting expressions at first.

And you had better learn with informal or oral expressions, and then try to honorific expressions etc.

Let's have fun with learnign Japanese ^^

See you,

Hanako

Great ! Nice try :)

First of all, there is no particle "わ” in Japanese.

I know you made a mistake, that's because you actually know the rule that when you use は as a particle, you pronounce like わ.
Also about "ぼく", usually only boys (especially little kids. Most of guys use おれ) use it.

Besides you wrote in formal way which includes です、ます, so you should use わたし.

If you wanna write in informal way, you could use ”わたし、あたし、うち" since you are a girl. 

Good luck! : )
