Is this bad embroidery?

I ordered a custom embroidered outfit for my baby from Zara and had the first one replaced because it looks bad to me. The second one just arrived and it looks less bad to me but still kind of bad and bulky? I’ll probably have to put a bodysuit on my baby underneath bc of the bulk on the backside. The backs are totally different on the two. Is this just how embroidery is or was the second one done wrong?
