Dude any time you are a skilled artist. Art is my passion whether it be music or fine art. I love to see people creating fan art for something that can be so beautiful. Lot of times fan art is more compelling than even the studios! People love your work man! Keep it up. I used to do things like this for world of Warcraft but then I got old. I would have loved to go to art school but now I'm currently an engineer and project manager. Don't have Much time for these kinds of things so I'm loving it and living vicariously thru your art. I'd love for you to draw my titan or something one day. I'll but on my best gear and stand in the tower for you like a model HAHA
