I feel slightly uneasy about seeing someone who seems to be a beginner being criticised online. It always takes me back to what happened to me when I was about 14 years old. Here is the story:
I made a tiered skirt to the best of my (very limited and self taught) ability. We're talking about the late seventies here, advise and guidance was hard to come by, and no-one in my family knew how to sew.
Anyway, I worked hard on the skirt and conquered gathering a 3-tiered skirt and was happy as Larry about my accomplishment. I wore it with a cropped top to spend my birthday money and some money I saved working during school holidays in a fabric shop. While queueing to pay, I couldn't help but overhear two ladies behind me criticising my skirt loudly, commenting that 'she should at least have matched up the seams'. The 14-year old me had no idea that one should do that. I went home in tears, took the skirt apart and re-did the tiers, matching the side seams. Before doing that, I actually thought that maybe I was just not good enough to sew...
Until today I only ever criticise someone's sewing when specifically asked to do so. When asked to comment on the quality of something expensive friends bought, I am usually vague when I think it's no good - why hurt them.
My students, especially the beginners, I usually ask "Are you happy with that?" If they say yes, I ask "Is there anything you'd like to look better?" Then I show them how to improve and let them grow.
I still remember how horrible I felt when I left that fabric shop 41 years ago...
Sorry for the long post
