Oh god. So that's the difference between something turning out good or not. Things that you take your time on turn up good and things that you don't end up bad. I try to spend only an hour on something because I'm lazy and unmotivated and it's quite noticeable that my doodles are messy and not really appealing. Not as they should be. I honestly don't think I could spend time like that. I'd go crazy.
Hahah yes I used to think I needed patience for a painting but I just plug into my ipod and go at it. If it's something you love to do then you get sucked it. It becomes addicting and soon enough it feels like only a few minutes. Your work is good but yes the time put into it helps a TON.(:
