WELCOME TO IMAGEFAP !
You, sir, are an =ARTIST= !
You've made a new FAN and I'm making your album one of my favorites.
As for myself, I've done some simple coloring work. I found this picture of a B&W wolf a few years back. Looking on the internet today, I see a color version exists, but at the time I had mine, I didn't know how to find similar images on the internet.
The original wolf can be found HERE: http://dw817.deviantart.com/gallery/?q=wolf#/d2xp2yk
And the one I colored HERE: http://dw817.deviantart.com/gallery/?q=wolf#/d2xp3c4
But as for adding items like you've done, that is quite difficult for me. I use Paintshop Pro 7 and I know there are better tools out there, but not those that are so keyboard-dependent as it is. I'm not very good with the mouse and prefer to use the keyboard for everything if I can.
You, however, have done some incredible work yourself, first class, and if you are not yet a commercial artist, I would certainly pursue it for your maaad skillz !
