Now this is the sort of army I really like to look at...buying what you like rather than feeling obliged to stick to the same manufacturer.
Excellent work all around and what a characterful force!
Regarding the bases...I didn't notice they were different until I read it...I was too busy looking at the minis!...so you'll get another 'leave them well alone' from me.
All I can add is...MORE!!!!, MORE!!!!, MORE!!!!
