Yeah if you want. Here [link] I tried making my psd as base like as I could in case anyone ever did ask so here you go. Just so you know the head is tilted a slight bit up from the normal ones so watch for that as you make yours.
In photoshop if you choose image size set it for nearest neighbor instead of bilinear or bicubic or whatever it is currently set at. Or in the general preferences set nearest neighbor as default for size, skew etc. For other programs I am not sure but check under the preferences.
