I think his work in Macross shows that he is maybe running out of ideas when it comes to developing Valkyries. The VF-25 looks like .Valkyrie Remix' - Mostly a VF-0S mixed with the SV-51 and some YF-19 as well. It is possiby his most refined Valk to date tho and a beautiful design. Shame that Yamato won't be releasing a toy version initially tho. Hopefully Bandai will come through.

I think his recent work on KISS-DUM is a better testement to his mecha skills. Other recent series of note are Aquarion, Eureka 7 and Armoured Core (game).

I'm not sure how much blame you can attribute to Kawamori for the changes to MP-3 (sans color). TAKARA had a prefectly good mold ready to go and then they bought him in... why? He didn't just kick in their doors and demand that changes be made - he was hired to MAKE changes because there must have been changes that TAKARA wanted made. They must have given him some sort of re-design brief.

My personal theory is that the design for starscream was a part of the Decepticon BINALTECH series that TAKARA was exploring. BINALTECH was cancelled and so the Starscream design was bought into the MP line instead because work had already been done on it to extent of being production ready. MP-3 really looks like a modern update of the F-15 that is asthetically more reminiscent of the BINALTECH series as far as the Japanese Samurai armour goes.
