the stitching looks good. I like the fact you lined the back of your wallet, many people forget to do that and it adds a lot to the overall piece. you kept your tooling simple which is good for starting out. Practice you beveling a bit more, the action with bezeling is kinda like a jackhammer, but lighter. a veiner would bring out the some detail in your vine work, but that comes with practice. What stamping tools do you have? the flower in the middle is clean and simple, I like it. Overall not a bad start wallet at all. keep up the good work.
on a side note, your liner leather can be very thin, even a fabric will work which will make it easier on stitching.
