I solve them too =D=D=D
This because i started to play Team Fortress 2, because MANY people in there asked me for a Team Fortress version of my Ota, and because, what else can Ota be than an Engineer XDXDXD ? I mean, he draws, collects modelkits, drives and fights in giant robots, this makes me think about mechanics, and in Team fortress the mechanic is the engineer, that's why he's one XDXDXD.

Btw, i don't play just as the engineer in Team Fortress, let's just say is the class i enjoy more =)=)=)
