The opinions vary. Some find my handwriting absolutely adorable and neat, others find it a horror to read. I tend to write really small, but straight, so my letters don't bend down to the left or right.
It also depends on how much care and time I give myself. If I've the time to write I try to write bigger and neater. If I'm rushing, like with my notes or exams, I always start out neat and then end up scribbling down stuff that are bordering towards that of a 'doctor's handwriting'.
I would love to 're-learn' calligraphy though. I used to write with a fountain pen, but then I moved over to the cheaper utensils and ... yeah. Nowadays I find my calligraphy handwriting look like 'crap', as it tilts a little bit too much to the right for my liking.
