This definitely a really good show here. The chimera screams standard issue I G hardware as much as the leman Russ and the lasgun.
As for my voting, as stated, its very close to call. The standard is always high from Wuxiong, the good Dr. Fugitive and Markay (those graffiti markings are hot!).
Lijah Cuu and Raukov, who are relatively new to the forums are all about the cool here, with awesome paintjobs (raukov also has dropped in some smooth conversion work for a very subtle change to the chimera, that kicks ass without changing the overall profile of the vehicle).
Chosen man has a particularly bling chimera, sporting nice forgeworld goodies (the stormtrooper tank commander is one of my favourite models, I can never get him to sit in a cupola however, so kudos!) and a cool blue scheme. I didn't have the guts to paint the 40th corps vehicles blue.
Lasblasters Chimera is pretty sweet as well. I love the way the metals are painted, they have a nice burnished look to them.
Lt Haller has the most be-atchin hunter killer Ive ever seen. Striking paint scheme as well.
deathfang23's chimera has definitely been through the wars, the blown off front section of the tracks is pretty cool.
Lt. Pliskin AJ has got nice simple weathering touches, the impact craters are very stylised and the stowage looks well placed, which is something I struggle with getting to look right.
