i think working on a chop over over a hour is a pretty good effort
Time spent is all relative.....for some an hour is a long time, for others it is just a fraction of the overall time they spend per chop.
I'll go ahead and be the one to sound like a jerk....
Your end result on the bear chop looks pretty good, but... it's not a very original idea. It is just following a tutorial step by step, with no other modifications... my tips for what would have probably brought in more votes are:
You could have found a different piece of trash paper and still followed the steps in the tutorial
You could have used the tutorial but changed the background, and possibly even added to the theme of it being a garbage source, so that it is not so recognizable.
