This mural is by Jacquelin de Leon (https://www.jacquelindeleon.com/). It is under Park Ave. on the Guadalupe River Trail and is really comforting to me.
Maybe this is why I am including so many photos and can not settle on fewer; I appreciate this comfort right now.
The artist said that this is inspired from being a kid in the bath with all of her sea animal toys and imagining herself in the sea with them all around her and then recently going to the ocean and wanting to sit in there with all of the sea animals (https://www.instagram.com/p/CdeHF4IPWbu/). That makes me smile.
