Creeper Planter

So basically I took the Creeper base from nova skin, downloaded it to my laptop, then uploaded it here. From there I just edited it to where it is now.

Just a creeper planter. I wanted something based off the Creeper, Aw man! meme, as well as something that would look good on a server.

QUICK QUESTION: Am I allowed to post/upload skins that I posted on Nova Skin? I have about 40-50 skins on there that I would love to share with the community. If I can't post them but you still want to see them, just ask. I have fruit thanos skins, a few OC skins, and some shrek and derp skins.
