Not too odd in my eyes.
The only thing is, that he should have used not just one GND symbol.
GND in top right should go bottom right and not point upwards.
Then, the horizontal connection in the top should go, C1 moved to J1 and C1 have its own GND symbol. And finally, GND symbol for U1 pin 2 close to U1. Thus the GND connection on the very bottom can go.
So the only oddity is not using the GND symbol as a replacement for GND connections.
So not too bad for a first time.
And well, the ERCs should be adressed before being able to call it “seems OK”.
