Fantastic job paint job, Paul v2 - and you really show us the quality of the WK-dwarfs. Would have thought you would have needed a bit more contrast, but the colour scheme works quite well.
Diagonal basing works well when done for display and for doing great on pictures as it gives you a bit more space between them. Gaming wise it looks a bit wrong, though. Moving units across the table that are turning their heads in another direction looks ... kind of stupid (IMO) - so guess I'll base mine on round bases to solve that problem
