That Kislevite ranger was from the period when practically the only new models for Mordheim were 1) WHFB rejects (like the Averlanders & Shadow Warriors) or 2) what I suspect were trainee sculptors being given 'practice work' on the neglected ranges. Both Mordheim & Necromunda got rare releases at that time, often so bad as to be insulting to the put-upon fans of Specialist Games. It still winds me up to think of some them...
That said, you've done a good job on her! Nice work picking out the musculature of the arm, & the bowstring's a fine detail.
You don't need five Tilean marksmen, but when they're so nice why not have them? Contrasted with the Kislevite ranger, I'm pretty sure those models were from a period where GW invented WHFB units to fit with what the history-nerd sculptors wanted to make. Great work again, with lovely bold colours!
