I'm not a professional, but it doesn't take a cook to let you know if the soup needs more salt.
Your panel pacing is fantastic, very easy to follow, straight to the point, and visually pleasing.
First glance through, I wasn't quite feeling the smiles on the guard's helmets. However, after a few more glances, it gives a very disjointed feeling to our (assuming) protagonist getting kicked out of the city. You got the body language down perfectly.
My favorite thing about these pieces though, is the fact that the ground/road is very well maintained close to the gate, but shows heavy dilapidation not too far away. From these two pages, it feels as though Shelter City is a very clean and sterile place.
LOVE the doors closing to reveal the title. Your compositional elements are very strong. I'd love to see an inked version. Your lines are very strong. Keep going!
