What a project. I worked for 45 minutes before the Steeler game and made little progress other than a fair amount of sorting. The split tendril shapes for some reason make everything significantly slower and harder. In theory one sorts pieces according to the pictures on the wall and just knocks it out, should be easy? Then this shade of lavender looks much like this shade of lavender. It does take a while to assemble all the parts and put all the parts together. This puzzle is not trivial or child's play.
The art on the wall is great fun: self portraits with hadrosaurus, Margret Thatcher, sea monsters, a regular galactic travelogue. I enjoyed all that. The art work may appear childish, however the puzzle is not. For me it required a while to get any traction. First the refrigerator, then the alien at the table were not too bad. Then one by one I put together each little art work and filled in in between. Maybe 292 pieces in 200 minutes the puzzle should only rate "Average" difficulty, however let me assure you one must work for nearly every placement.
Naturally the colors were clear and bright, easy to work with if you will. I am not put off by the difficulty of the puzzle, lets agree I was pleasantly surprised. I got my dimes worth of entertainment out of this puzzle.
