Nice! You did conjugate really well.
When you conjugate a verb, sometimes the subject will implicitly be known. For example, "Yo estoy comiendo galletas", [estoy] is conjugated as a single singular person, so "yo" is a bit redundant here. It's more natural to say "Estoy comiendo galletas". You will know that better with practice.
Aside that, very well! Keep up the good work :)
