That's an interesting tree.
It's painted tho so can't really tell much from the way strokes have been done. Seems pretty straight and orderly so I'll say it's a pretty stable and confident person.
There's a lot of spikes there. That suggests aggression. Especially against the exterior world/strangers. You can see the grass is pretty pointy too.
The soil-line is missing completely, which suggests someone more keen on ideas and theories than then pragmatic facts.
Page positioning is central and pretty normal, so that's just normal.
No roots suggest no childhood doesn't really have any influences on you atm. Amnesia? Or maybe you've just gotten over it, dunno.
Trunk's pretty straight and normal, no under-evaluation nor narcissism.
The branches are self-intersecting a lot, which means there's a lot of internal-conflict going on. Having the leaves of the tree inside, surrounded by some outer branch also suggests you're not looking for new experiences, and somehow you want to protect the memory of the experiences you've already had.
Having a sun indicates some artistic ideas coming from you, and also optimism.
Dunno what that black spot's supposed to be, maybe some danger/omnious thing looming over your existence?
Disease? Death? Some event you're fearing?
Anyhow, that's pretty much all I can think of for now.
That's actually pretty accurate.
The black circle is just covering up my signature.
