私はいこです。私はまだ日本語をべんきょうします。*

---

* Since you used 「です」 earlier, this would point at you speaking in formal form, therefore you have to keep doing so through the entire text, unless something were to happen.

And it may be smart to use 「私のなまえは」　instead of 「私は」　since いこ　sounds like いいこ（いい子）　which means a good child, nice child, etc etc, you get the idea ^_^
