3D Low Poly Dagger

Wolfer

Hi there. So this is a dagger I made following a udemy tutorial.  It was making a low poly weapon. Its not going to be used in a game but I wanted to practice making 3-d and using substance painter.  So want to show the dagger and paint job for it. I ask if there is any advice on how I could improve this dagger design in substance painter. I know I could do thing to fix the model but want to keep it low poly but wonder what I should keep in mind to improve or for next time. Thank you.
