Those look great! I don’t know anything about price and what not. Please don’t take this the wrong way, but have you considered painting for children’s books? I love to see beautiful artwork for children’s books!! Think Paddle To The Sea..I love those pictures. And Robert Louis Stevenson’s book of poems w/ Tudor being the artist. Oh my, those paintings are wonderful! Your tree painting makes me think of a quiet lovely place of a poem!
So I am not saying you couldn’t sell them anywhere you want to..I am saying I wonder how easy it would be to paint/draw for children’s books? I am actually complimenting you! I hope it sounds that way!:)
Maybe you could try your local gift shops to ask if you can display them there?
I would love to draw/paint like that! Always had an interest! How would you like to teach me? LOL!! What a great idea to earn extra money!
Blessings!
