A few years back there was a guy in the local IPMS club who was 'creative'. He adorned his models with found items and hunks of sprue (not stretched sprue, cut-offs of sprue). He brought a frame of sprue with the parts cut out. The airplane form was interesting, but ... His stuff wasn't well thought out like a Borg cube, it was just thrown together
His creations were crudely assembled with glue marks showing. When he painted, it was by hand with many brush marks and or fingerprints..
He never did well in any competition because the others in the cateories were better done, craftsmanship, assembly, painting, etc. He never listened to our critiques on how he could improve his work. He was happy with what he was doing
If you desire to play in the IPMS arena, or almost any other organization's competition you have to understand the rules and agree to play by them. If you can't play with them, then choose not to play or work to change the rules.
I have no problem with a red-painted tank or a chartruse aircraft, or a polka-dot Arizona (at the height of the color controversy), as long as the craftsmanship of the assembly is there. Seams addressed, alignment correct, paint has no runs, no drips, no errors (to quote Johnny Bench and the Krylon commercial. That is the gospel that IPMS has been preaching for more than 50 years. (And its always better if you have photo documentation of that red tank ;>)
