Yo! It's a great start, but you need more work here. The lines aren’t properly converging toward the vanishing points, mainly because there isn’t a clearly established horizon line. Because of that, the vanishing points aren’t positioned on the horizon line. That’s why we see the lines converging toward different points. You can even notice that the mannequin of the character is also converging toward those vanishing points. So first, establish the height of your horizon line. Since this is a low-angle view, the horizon line should be placed lower so that the vertical lines converge toward the upper vanishing point. Remember that parallel lines converge toward the VPs along the horizon line. Even if you rotate objects, the vanishing points will move along the horizon line, but they won’t move outside of it. Hope this helps!
