you can, just edit it in with whatever art program you use to make a skin, though with the low res of the images you couldn't do anything that detailed, so most tattoo's would just be a blob on arm or leg
The world's fate is in our hands, it's our responsibility to ensure that it's going in the right direction. We decide what to do now, and what we do now will affect everyone that comes after us. Our actions ripple through time, will we risk a worse future for everyone through pettiness, selfishness, and foolishness, or will we push for a better society for all? What I ask, do we peril, or do we prevail? Will we build this world from the ashes, will we further send it into ruins, or does fate have other plans for us?
