Im giving this Convesion a high rating, i think its vey well thought out and the peices look like they belong on this mini, but if i was to rate your painting alone im sorry to say id have to throw you a 4. Ill rate it a 9 though, since i love the conversion
Less shiny clothes and less metally arms (they look drybrushed now) would greatly improve the model. Also, it looks like you didn't highlight/shade the casualty helmets...why not?
