I'm in agreement with Guppy and Redhawk.
Basically you're wasting our time and skinning inferior skins based off of little-to-no actual references, and then posting about a skin you know will get criticism, so you're not showing us screenshots? It's like you're having fun at the community's expense.
I think I've got about 30 skins in this game. I can say I'm decent (not the best). My first 2 skins were rejected flat out. I know what it's like to start out in this stuff. The problem is you need to go back and rework something "here" or "there" but instead of even daring to see if there is anything wrong, you hide your skin away.
Frankly: If you're too ashamed to have your skin see the light of day, why did you skin it in the first place? Start with showing WHAT you will skin first, in the forums, and if you don't have any info on it, ASK. Once you're sure the skin is valid and worthy of being in-game, then proceed. Show progress, even if you KNOW you're not done, put up a screenshot or two (just for the fun of it). Keep working on it until you're HAPPY to show others in the community your screenshots. Then when you're TOTALLY DONE, step away from it for a full week. Not 3 days. Not 5 days. A week. Don't even look at it. Come back and start over. Look at your detail layers, your weathering, the final in-game product, and make some changes. Then step away from it for ANOTHER week. When you no longer see any changes you want to make with your "fresh eyes" ask the community. Some suggestions are subjective, but some are quite eye-opening, and you realize you've missed something important.
