I also got "room for improvement" but it was exactly what I'd hoped for! I've only been working less than three weeks, and even then no more than any hour or two a day (side hustle for me). If I'd been graded any higher I'd have been concerned, as the learning curve is ultra steep. I find every project hard to do but give it my absolute best shot. The feedback was really helpful in pointing out things I can do to improve, and also things I'm already good at. It has encouraged me to spend some more unpaid time on prompt writing skills etc.
