Most skins that are actually good will usually after a few minutes, (because of the amount of skins being uploaded) Are usually going to get lost in a sea of teenager skins within a matter of minutes. What I suggest for you to do is to create a texture pack. Because texture packs are the most difficult thing to make, there are not as many being uploaded at the same time as skins. Once you do that, you'll gain a lot of downloads, diamonds and tons of subs. With the subscribers, you'll be able to upload a skin and so all those (300 subs) for example can see the skin and interact with it.
Hope that helped.
