It's a good start and there is plenty of room for improvement. One piece of advice I'd give is try to get your hands on some handwriting practice paper (for example). Your lower case letters go up and down in size, whereas ideally they should all be of equal height. Handwriting practice paper has a dotted line in the center, so it makes it easier to keep them all the same height. Once you master that you can go back to regular lined paper and because you've developed muscle memory now, you'll see great improvement in how all your letters are of the same size.
Good luck! With a little perseverance and plenty of practice your cursive will be the envy of your peers (as mine is with my peers 😀)

P.S. as many have already added below, stick with fountain pens if you can. Ballpoints just make even the neatest cursive look horrible)
