I always choose this pattern of artwork because I believe in utility and the message an art pass to the public. The durability of an artwork is what matters to me not just something that has a limit utility. I create artwork for Roobet with great designs and texture for better durability but it seems no one cares about that.
What matters the most is the output based on the theme of the art contest. Now matter how durable or the technicalities involved in creating the artwork, if it doesn't reflect the criteria being requested, you are most likely going to lose.
Remember, technicalities alone in creating the artwork won't suffice to win a contest, it has to be a combination of all other things such as the concept and mastery of the medium being used. Just stick with how are you going to create a piece based on the theme without violating your own set of rules and you'll do just fine.
Anyhow, I appreciate your artwork @Bushdark. Keep em coming.
