Interesting mini with impressive ideas. I like the dirty-rusty metallics (although in some places the surfaces are to similar and you can't clearly see the details - mayby some stronger blacklinig or contrast washing of different colour would help). The fire from the flamer also might look brighter. And finaly the element i like least about your minis - the cables made of wire. They look unrealistic in my oppinion. I mean the edges of the curvatures are to sharp, they should be more circular if they are to imitate wires, else it looks strange and rough.
Overall its 8,7 for me. Although I don't like some solutions, it deserves a high score for originality of style and great use of metallics. Bohun
