Hi,
I think it's looking very good! I would not be worried about the minor flaws.
I'm glad to see a relatively small container for the plant. Watering too much seems unlikely.
Is there a hole/can you allow water to drip if there is too much?
Probably likes as much light as you can possibly give.

I've only grown a banana, once or twice, outside, whole different thing.
