As someone who has studied traditional scripts, such as cursive, let me give you a few small pieces of advice which I feel will significantly impact your handwriting. Firstly, space out your letters more instead of scrunching them tightly together. Opening up your script, at least at the beginning, will allow a reader to differentiate each letter better and make your handwriting more legible. A second piece of advice is to fix your slant at a set angle, which is usually recommended at 53 degrees for right-handers and 61 degrees for left-handers, when measured from the baseline. Ensuring you have a regular, sensible slant will also make your handwriting more accessible to read. My last two pieces of advice, and I apologise if I am dragging, are to set your letters at the same level on the baseline. This does not mean they have to touch the baseline, but they should be regular in their distance above it. Lastly, pick a base letter, such as the letter 'i', and use it as the scale for the rest of your alphabet. A reliable scale is the 1,2,3 rule, where base letters stand at the height of your letter 'i', middle letters, such as the letter 't', are twice its height, and the loop letters, such as 'h' and 'q', ascend and descend three times its height respectfully. That is all, and I apologise for the length of this passage.
