I currently have a massive backlog of about 40 unpainted ork boyz, 10 gretchin and the runtherd, 3 nobz, 3 meganobz (one is a big mek but for now I just use him as a meganob proxy), and an ork trukk and I bought a new battlewagon today that I'll need to assemble and paint. This huge backlog was because I didn't have much motivation and my main paintbrush was completely ruined, but I hope to base coat (I rarely highlight, with the exception of the flesh) the majority over December and the rest of November, however I am busy so I may not get a chance to finish them all by christmas. It's quite late here in Britain so I'll post some pics tomorrow.
I also earlier bought a replacement brush and a few new paints to try out.
I think that my lack of motivation came from the fact that they were always stored in my crusade case and it didn't make much difference whether it was painted or not as I only saw them occasionally. Now that my new shelves have arrived, I can see them a lot more, and the painted models look really cool, even if they aren't fully painted.
