Very pretty and I think painting with all similar colors makes you concentrate more on value. Oils are really tricky, especially when it's all wet on wet! I think if you want to venture into oil painting again someday you should allow yourself a day just to get form, then another day just for value and then finally spend the rest of the time getting it to look like you want! Acrylics are quite a bit easier that way because they dry so much faster but I do love the richer look of oils! You've come a long way! (And the background is lovely!).
