Looking for Constructive Criticism

Hello all, I'm looking for any and all constructive criticism. I know I have a lot to learn when it comes to leatherwork so fire away.

What you are looking at is what I call "practice pants" 😜, it's a prototype of a small Gladstone bag that I designed. Although it's so basic I feel awkward saying designed, more like made my own pattern. The leather I used was cheap 2oz- craft/veg tan from Tandy.

I will start it off with-"Next time when sewing the stiffener to the bottom panel remember to use the leather feet you purchased so as not to leave a race track on the bottom of the bag." 🤣
