Firstly, your penmanship is great, better than mine as a native tech worker.

For some actual feedback, your letter sizes for the same letters are a bit inconsistent. That just takes practice.

You are writing at a bit of a slant. That is not wrong but not that common, at least in the states.

You are trying to stay within the lines and that is causing you to change the shape of the letters if they are too large.

Your f's could use a bit more curve. They look a little close to a t.

But seriously it looks great.
