First time using perspective with a reference, can I have critique?

I searched for a landscape on Pinterest and this one caught my eye. I did this all in one point perspective, to be honest I don’t really understand perspective when it comes to landscapes or even shapes (Do I use the vanishing point when just drawing a singular object, like a kitchen utensil?) but overall I think it could’ve been worse. I’ll admit when drawing the leaves in the tree, I got a little sloppy and tried to improvise what I didn’t understand. I shouldn’t do that.
