Gorgeous! The vibrant colors give it such magical feel. The lack of defined textures overall would normally limit the readability, but I think the way you utilize it here gives it a very painterly look and it compliments the subject matter. Your composition is strong, it leads my eyes around and there is lots to look at! For the shading on your trees(mostly the big one), I think you could add a little bit more rim lighting to the right edge as well. Not too bright (maybe just green instead of yellow?), and just sparingly. Also a little bit more highlight on the tree trunk too! Very beautiful overall, great work ❤️
