Your handwriting makes a very negative first impression, but shouldn’t have your score lowered as long as:
1. there is no strain to read the handwriting and words can be clearly read
2. cross outs and inserts can be easily followed without causing strain to the reader
I think you probably fit the above two criteria, but note that your handwriting still makes a negative psychological impression that may cause your score to be reduced somewhere.
