Your lines have a bit of wobble to them - this may be from low confidence in drawing your lines and/or trying to correct them to hit the end point before you've reached the end point. To improve, slowing down on ghosting may help (it helped me significantly). In addition, once you've put your pen down, commit to the stroke all the way till you've lifted your pen. In a way, this will help you see how you can improve on the next line (for example, if you overshot it, you can try stopping earlier. Or if your line ended above the end point, you can try angling it lower on your next try).

Your ellipses are quite loose and they don't touch each other or the frame or both sometimes. In terms of looseness, It seems like you realized the ellipse won't touch others/frame sides, so you may be trying to compensate on the second loop. Try ghosting more beforehand, ghost-touching the neighboring ellipses and the frame, before putting down your pen to make the ellipse. Again, once you've put your pen down, commit to it so that you can see how you can improve on your next attempt.
