Giving you "props" will do less than what they're giving you right now... If you know it looks terribly god awful that should give you more "drive" as i should say to make it the absolute best of your abilities and to learn and not release it as soon as its finished. It should make you finish a project but not release it considering you want to learn more about what certain things do to a truck to make it look better. I haven't released anything in forever but I've got 3 completed trucks in my folders that i just keep updating with new stuff I learn, and they probably won't be released until i figure a few more things out to make them look as good as I can make them look. Now on the body skinning part, you just have to be open to anything. Start painting without an idea of what you want your finished project to look, and try to impress yourself.
