After thoughts... I had the smoke taste in my mouth most of the night after cooking so I think next time I will put about half the amount of hickory or mesquite chips in...
I find it's hard to oversmoke with hickory, but easy with mesquite, IME.
I smoked 3 boston butts (2pm to 8:30am) a couple of weeks ago and thought I was going to overdo it with the hickory but I found the smoke slightly lacking, I wish I'd have added mesquite with the hickory (a lot), maple, & apple.
Your smoker looks good, and since you're cooking with what appears to be a similar device to mine I'll link you to the virtual weber bullet for some more recipes to try!
