Don't listen to Camel. Pandas are extremely overdone and annoying.
While I will say this, your skins are not bad, but not something I'd use, but that's because I'm a picky person.
Your skins all have a general same layout, but that's because they're green, so they all look very similar to me. I suggest trying out new things, different characters of sorts. I usually add noise to my characters instead of shading them only because my brain doesn't function in colors correctly, so I cannot shade worth a damn. I use MCSkinEdit to make my skins. It's very basic and suits my needs very well.
I can tell you're looking for some people to download your skins. So here's another tip. Why not make a skin of a character from a series you like. It could be vidya game, movie, tv show, cartoon, anime, etc. Why not Minecraftify a favorite character? Make something you'll like and you'll have fun doing it. Don't worry about not getting many views/downloads. If you'll want those, make something extremely overrated, like a recoloured creeper, or some stupid zombie in a suit.
