In common with feedback from the other guys in this thread, I really like these small vignettes as well. I was a bit intimidated when I first began posting here, kind of half expecting my efforts to be greeted with raucous laughter - but that simply doesn't happen. What does tend to happen is that the newcomer is warmly welcomed and where appropriate offered advice, help and assistance that allows us to introduce improvements into our work. At least, that's been my experience here.
Everyone has their own preferences as to scale, era's, mediums (white metal, plastic, resin), and so on. I tend to concentrate on 54mm with the occasional venture into 75mm. I do have quite a few examples of 28mm ~ 32mm in my vast grey army, but haven't got around to them as yet. This year has been a complete hobby washout for me due to completely insane work commitments, but these ought to calm down by the end of 2013, allowing much more time for painting and diorama fun next year.
So, catdancer, welcome to PF and I hope to see more of your work being posted here. Believe me, these smaller scales scare me and I hope to pick up some hints and tips from you on how to make these "pop" in the way you've shown with these examples.
Cheers
H
