Hello to all people

Hello, im new, i like sonic so i wanted to join here. I want to know if I can use my character like Shadow (Its with different colour and idk if i can use it) and another character like Sash lilac (Its with different colour too) just for know.

Hello, welcome to the forum 8D Could yoouuu.. elaborate a little?
You mean that you have a character that looks similar to Shadow the hedgehog? Is that the only similarity??

I mean, recolored characters IF i can, because i am not good doing fan characters

You are free to have your character look like a recolour of a canon character! We have quite a few people similar to canon charas here anyway. The only important thing is that your character isn't RELATED TO a canon character in ANY WAY, so they're not friends or family or anything like that.

When it comes to pictures, recolours are a bit more frowned upon - you can submit a recoloured OFFICIAL artwork, like from a game or from a cartoon, if you really need to (but you don't have to post your character's pic if you don't have any). But you absolutely CAN'T recolour someone else's art and post as your own - that will result in a highly possible ban.
