Here is my Entry to the Size Matters Category showing a small Rebel force (a sniper and a Jedi) attacking a small Imperial Outpost defended by Marrok and a Scout Trooper and Storm Trooper.
Overall the the MOC measures 24 studs in length, width, and height including the backside of the MOC. There is minimal overhang for the rear end of the speeder bike and elements of the explosion. Moreover I've tried a variety of techniques that are still new to me such as lighting and the explosion. The most complex and rewarding part of the build was the SNOT flooring pattern of the Imperial Logo. I've actually been working on this technique since February and finally was able to get something recognizable.
I usually don't work within a size limitation, which provided a unique challenge. Similarly getting the right photo angle was a point of struggle, representing the size constraints and showing as many details as possible. While the final result is not perfect, I am still happy with the result.
Thank you for viewing and enjoy your day!
