Both beautifully painted, wonderful expression in the sky, flowers, tree and grass. Both enchanting with their quite distinct moods.
The only thing I'd say just from a personal POV is that the main body of the tree is quite dark in comparison to the rest of the scene. This may be a definite effect that you want to achieve however.
The Spring one is charming and the moody darker one holds quite a lot of charismatic tension.
