Hi! You could rotate the upper pieces of the tree to so that the lines aren’t so symmetrical, then loop cut the trunk and misshape it a little bit. Then after that, select a few vertices from the upper part of the tree and raise them.
Try and resize the trunk, and whenever making a tree, try and give it some more detail with the leaves area as it, in all, will look so much better. I do not know the style of the tree but I would still recommend making the color scheme a bit more, realistic…? In all though, great work!
I’d definitely make the trunk of the tree smaller, it’s too thick and doesn’t look that good in my opinion. Other than that it looks nice and simple, great job!
I’d recommend decreasing the size of the trunk. Also changing the color of the tree to a darker green would look nice. I’d also make the top 2 leafs of the tree a bit smaller, and also add another additional leaf. Some other details would be bending the trunk a bit and maybe the leaves, and also making it abit more nature

Other than that i’d give it a 5 out of 10. Great job and I hope to see some more improvements from you. Also, you are in the right category!
If this helps, here is a trees I modeled and you can see the clear detail and maybe it’ll help improve you’re tree.
What I would do is make the trunk more detailed (more curves, a bit more into the ground, maybe raise the leaves a bit for a taller tree). And I would also bend the leaves a bit so they are not all in one direction. Overall its a great start!
