Myth of the Siren Picture

Did this a couple of months ago while me and my family were on the boat. I was inspired to draw a mermaid and thus this art piece came out of it. xD Mermaids are very fun to draw, even though I don't believe in them. So enjoy and give me an opinion please if you have some time!
