I say you nailed Him well, and same with the saint. If you need more inspiration on Jesus' proportions, old paintings from Masters of art like Da Vinci (uploaded for reference) or even Michelangelo are great examples to look at.

Jesus with Saint Liborio
Notas do artista:
A seminarian commissioned a drawing from me. He asked me to depict the scene with Christ and Saint Liborius in a forest. However, I wanted to know if the figure of Christ is anatomically correct, and the rock on which he stands is also decidedly low. As for the rest, I think I've created the landscape with good perspective. If you see any errors in the drawing, please feel free to correct it. I'd be delighted if you could, especially since I want this drawing to be beautiful; I don't want it to contain any errors in perspective or anatomy.
