Looks good. I have a similar smoker and have greatly enjoyed it! One thing I would do if I were you is oil up the underside of your firebox lid if you have not already with some bacon grease/pam/canola/whatever. It looks like it is a little rusty and you want to prevent that from eating through while not in use.
