I think this is a good effort overall. I quite like the visual interest and shape language going on with the leaves. I feel your trying to tell a story in here, perhaps about new life and growth. I see elements such as the egg shell and flower among the decay and frost so I am presuming that's what you had in mind. Nice concept overall.
However I feel the piece is lacking in places too. Your composition is haphazard with many competing details and lines of action that are leading the eye everywhere, but not everywhere in a flow. Its too busy and there are no quiet areas. The flower in competing with the egg shell, and I feel it would be stronger if the flower was open and facing towards the viewer.
Your approach to materials is not quite there yet. Everything feels the same. Perhaps spend some more time to separate out the main elements. The frost could do with more impact as light catches it. Its too dull.
I think a strong value statement will help with the storytelling. Push your values more. I think your colours are OK. It would be more beneficial to push those values as I mentioned, although a bit more reds and oranges with a push for some blue in the shadow when you get the values sorted will help bump the impact.
Overall, I don't think these things are beyond you, you seem to have the technically ability to pull it off. Hope this helps and best of luck. Happy painting!
