Nice job,since it's a WIP-(It's a WIP right?) There's no coloring for now(i guess)
I love the 3D effect,but i have the feeling that something is missing,take a look at this,

This is for now,my bigger project of set, i started it after ending the terran compaign on Starcraft,inspired by the Protoss.
I restarded working on it 2 months ago approximatively,it was too hard with gimp \:,i ended this with photoshop.
