So I hand drew this lady and took a photograph of her on my phone. I opened it in Affinity Designer and traced the image in a couple of different layers. While I was tracing the image the pixels seemed fine but at some point the image started looking really pixelated and I don't know what i've done wrong. I've tried looking for solutions on Youtube already but none of them are helpful to me at the moment. I'm still very new to the software and to design software in general. Any help would be great, or advice.
