A quick drawing I did with the tablet my friend loaned me. this wouldn't be possible without him.

 

Simple...but interesting.

 

That looks awesome!

 

Love the choice of colors..any plans to add more?

 

Looks pure evil  

 

I might add some detailing that looks more like the movie design's "lava" armor. I could probably attain something like that with the stained glass filter on a new layer. The background might get a cool flame treatment as well.

 

I really like this. The composition is well balanced, and the line work is dynamic  

 

Not very Prime-ish.. But that's one great piece of art, well done sir!

 

An update to the image. I made the flames a lot more dynamic. I might make another image where his other hand is out holding the staff.

 

I think I actually like the flames on the first version better; they seem more dynamic somehow, and fit the feel of the sketch better than the new ones. But it's a very cool sketch. The use of the mosaic texture on the eyes and highlights is really interesting.
Do that second pic, I have a feeling it will be awesome.  .

 

I have a Photoshop file for each version, so I might take the flames from the first (they're a seperate layer), and put them on the new version. I might touch them up using a similar technique for the new flames, like using blurring and liquify, but they'll look more dynamic since I hand drew the flames on the first rather than using a wind filter and blurring.
