Tanith and Ghastly sketches

I love these two! They're amazing and adorable!! :3    (Sorry about Ghastly's muscles, I'm not good with large builds)

So I sketched these two because I couldn't get to sleep ... Anyway I think that I'm just going through all the major SP characters and drawing them. Mainly because I'm more confident that I can draw their faces. :) Anyway who do you think I should draw next?

I don't own these characters, they belong to Derek Landy.
