Look harder. And there may be no legal rights, but it's definitely a courtesy. Plagiarism is plagiarism, and you're not liable to win many friends in the skinning side of the community. Now if you said in the first place what you were doing: Practicing your first skin by building it off the Default rather than leaving it to us to recognize that ourselves it would have been different. There's nothing WRONG with it if it helps you learn, but don't just come onto the board saying "Here's my new skin!" when all you did was change markings and insignia on the Default.
if I wish to modify skins of someone else, not in order to make a twisting, but just because the skin I wish to do has the same base i'm free to do it.
I never sayd i was going to send my skin to AH or something like that, just posted the work I did modifying the P39 skin, changing the green skin, modifying green camuflage, the belly and adding 72 st insigna. Did you never used based skins of someone else, insigna, colors ect?
As I have already sayd, on skins rules there's nothing about "never use others skins as start" and till it won't be written and skins still free to export it's not plagiarism.
Anyway, if one day i will have the skill to do a good skin, if based on someone else skin I will have certainly the courtesy to ask before to change anything
I dind't wanted to came to the board and hurt anyone, unlucky it's not the same will of those who have more experience.
If the words "Ok, that's my fisrt skin job, so don't hurt me " was understood as "i did all my self" then i'm sorry, my english isn't the best.
Have fun!
