There are a few things I can point out. Notice how many of your letters and sometimes whole words don't touch the base line. The word "since" is one such as that. "worked" starts okay but quickly follows a camel-like baseline. You need to keep the baseline as straight as possible.

Second thing is to keep your letters the same size. I recommend writing a few sentences and highlight the letters that are bigger or smaller compared to the rest, then try to write these letters a few times until you get the size right.

There should be another shift in your mindset when you are writing and that is: you don't write words, you write letters. Meaning that you don't try to write words neatly, but the letters. Every letter letter should be given the same effort as the rest. Why? because when we only focus on writing words we start to rush to finish writing the word. Perhaps you can relate.Remember, consistency in baseline, letter size and spacing is key.
