I'll try an get a comparison photo up for you shortly. I commissioned and sell these so I am very biased but of the the groups I game with everybody is using these with both Eureka and Empress figures.
You can see my figures from both of these companies in the book SKIRMISH SANGIN. Just to show you I own units by both manufacturers. My brief to eBob was to make figures that work well with both ranges and I think thats what he has done. They are cast by Eureka, so the quality of cast is great and of course designed by eBob who is just great. There's more coming soon and are now available in Australia from elite miniatures as well NZ and in the UK from Radiodishdash.co.uk. If anybody buys some and doesn't think they fit with their Empress/Eureka miniatures I will happily refund their money once they ship them back to me.
How about that for a guarantee.
cheers
Colin
