Hi!
first off, I love the palette that you used. How the color goes a little warmer when it gets lighter.
Zoomed in, I think it looks really good with the individual leaves! The shape doesn't translate very well when you zoom out though.
I think maybe there's a little too much detail, were the overall shape and form gets a little lost (with the high contrast areas near the top layers).
And also near the sides, you have leaves that seem to be sticking out at slightly different angles, which creates lots of depth, yet the front-facing bit seems a little too neat and orderly. (like what Eishiya just said, basically)
I really hope this helps! I'd love to see what this will look like when you're done : D
