Critiques!
First of all, very nice. For your first 'finished' digital piece this is an awesome beginning!
-The bandages are nicely done. Very stylized and they actually fit his shape and contours.
-I like the nonchalant, egotistical wizard pose as he shoots lightning out of his hand. The expression adds to this very well.
-The lens flare light source is casting the right shadows and highlights on his body. That can be tricky and I always mess up light sources so kudos!
-The feathers on his coat are great. I wonder if you could create some subtle reflections from the lens flare off of the feathers. I would hate to do it, being so tedious, but just a thought. They work the way they are now very well though. Personally I wouldn't change them.
-The background isn't much of a contrast to Jorumn. This attributes to Soul's comment on his left hand being ambiguous. It might just be the contrast on my monitor but it seems like its fading away into darkness. I don't think I would have noticed it too much in the new one if it wasn't already pointed out though. Lots of dark blue on dark blue.
-Pretty sure its the flare of his coat that makes his legs seem shorter. It widens his base, and the beginning of the flareout begins below his hips, almost mid thigh. This makes his torso seem longer even though its not.
-This might be personal preference, but clothes are wrinkly! Maybe I need to iron more... But his coat seems plasticy rather than flowing like a garment.
-Background again. It might be just the way I'm interpreting it, but there doesn't seem to be much depth to it. I'm not sure where he is, or if the bright ovals are part of the spell, but it all seems to be on one plane. If you allowed the highlighted ovals in the background to fade out the farther they were from the lens flare it would make the focus even more on Jorumn. But really thats just from idea rather than execution. I never do backgrounds
Keep arting! I haven done much other than doodling during meetings at work, so I envy your motivation.
