I got the current one of filly rainbow dash with a pacifier from a folder I download of images. I got it off ponychan.net. I can send you it's original size photo if you like or give you a link the the full nearly 1GB image folder of stuff relating to MLP:FiM.
As for the old grow lithe one with the transparent background it was a standard image converted by Antony. That can be found on my profiles message board here on Adisc.
Yes, I'm mainly into European weapons and armor. The stuff you see on the games like TES4:Oblivion and TES3:Morrowind too . Im really pumped to start taking this blacksmith course though. If i really like it, I'm going to build a forge in my back yard.
