Engraving animal pictures / Engraving Resin?

It seems that after Engraving the picture, about all that was left on the wood was the adhesive. It kinda rubbed off….
Tried doing a different picture and acrylic without the paper and since everyone said the first one on wood was too dark I lightened it up in Photos, but with no paper it was quite lite. Trying it now on the acrylic with paper to see the difference.
