Well I have resteemed the post when I first saw it :) which on steemit is pretty precious haha
Also have you considered making it a bit more blue? You can edit digitally, because you don't realize right away that it's a dolphin in water, when looking at the thumbnail of the post :)

Because I liked the color of the turquoise reflex T.T hahaha I had many problems to make this dolphin... I do not clean my brushes before starting

It looks clean to me xD
And I know what you mean, I'm terrible with watercolors, but definitely want to learn :D
Which is why I appreciate you sharing steps and resteemed it ^^

Maybe add like areas with blue, but leave main color turquoise? It should be easy enough digitally, with masks or erasing.

I was also terrible (I still am) but I love painting with watercolor... The thing is that you risk experiencing... is very relaxing and you can start with simple things like birds: 3

Haha, I should definitely try drawing some birds then ^-^
And you're really great! Looking forward to more :D

Thanks hahaha I will be here :3
