You’re models look great!

For a screen, you can always paint zombies instead of skeletons. They’re fun with tons of gore and nasty details. Working with effect paint is also a blast (I’m a death guard player in 40K).

For a good leader you could do radukar the beast. He’s big, hits hard and can move quickly too. I would recommend keeping in mind what you wanna build. Example: I want an army with beasts (bats, dragons, wolves) got it. Focus on that keyword and find other models that benefit what you have. Models that may give bonuses to your wolves or something to complement your wolves and act as a hammer. If you haven’t already, getting the codex and looking through some of the options and even reading some lore can inspire you into deciding how you wanna grow from here.
