Here is my recent attempt at using rare earth magnets for attaching bits. All arms and weapons are removeable so I can customize the weaponry for each battle. I'd love to hear your constructive criticisms.
The magnets are a really cool idea. It will be fun to switch out weapons on the fly and keep your opponents guessing what you will bring to the battle.
Using magnets is a pretty sweet idea. The paint job is a bit flat though. It could use some detail in different colours, to give it some life. The shading on the corners is pretty good, but the whole thing is just too monochromatic. Congratulations on a palindromic pic number (#42424).
