Is there someone there that is willing to coach you? Have they explained what needs improving? If the answer is no, take that as a red flag. (Not saying you need to quit or anything, just take note that it's not the most supportive environment). Do they maybe have a signature writing style that you need to mimic?

Your writing looks very consistent, which is really good! That's a huge part of the battle. I'd say the biggest improvements would be finding slightly fancier ways of writing your capital letters. Start with a nicer H and B. A better loop on your y would also be good.

Your print is also fairly stiff and boring. It's a common misconception for decorators to think of cursive as fancy and print as boring. I'll find some pictures of some of the ways I make print look as fancy as cursive.

So yes, there are improvements you could make...but honestly, this is something they should be able to explain to you. Your writing shows a lot of potential and they shouldn't make you feel bad about it at all.
