I honestly believe this is the most emotionally captivating piece of digital artwork I've come across in a while. You used excellent colour schemes and blending techniques - the fade from summer to winter is very smooth, and the single loner caught on the edge, sort of "outside looking in" tugs away at those heartstrings I'm also a big Sonata Arctica fan, and you've done "The Last Amazing Grays" justice with this.
I really don't think there's much (if anything) you could improve with this piece - in fact, if you tampered with it at all, I think it would lost its powerful emotional value, and the emotion behind it what makes it so beautiful. You've done an excellent job, be proud of this piece!

Really, I dont think this needs any critique at all! This is a wonderful image that is expressive, aesthetically appealing, well crafted and intresting. Your design and composition for this piece is lovely! The photomanipulation was done wonderfully and seamlessly. And the richness of textures color and light just jump out of the picture. You did a fabulous job! The only suggestion I can even make is a very slight modification to color in the upper right hand corner: In painting I find that it is helpful in making a whole composition feel unified to carry similar colors throughout the whole piece so that there is not an area that feels out of plae tothe rest. While the dichotomy between the warm and cold is obviously one of the main points to this piece - I dont think that would be compromised by bringing just a touch of the yellows or gold into the sky... maybe just as light behind the trees... but not enough to really change the tone of that side (barely noticble even) just to add a little unifying color so it doesnt split so completely intoseperate images. I think you already have plenty of the whites on the left panel, and see that you do have the yellow leaves toward the bottom right which all works wonderfully Where you transitioned between the two looks absolutely terrific! And the same can be said about the central wolf. Great job!
