[Blinkie Uchiha]

Suigetsu: he's awesome I got nothin'
Neji: if he was a bit less serious
Asuma: shave the beard ..
Shino: If he has more badass lines

 

[Etari]

Suigetsu: If only he would stop talking.
Neji: If only (like the other person said) he was less serious about everything.
Asuma: If he would stop smoking, like his wife said. If he had survived the Hidan & Kakuzu Arc, he would die of Lung Cancer.
Shino: If he could stop saying, "-naze nara" and talking random unnecessary crap.

 

[YellowFang]

Only Suigetsu and Shino need the improvement now, since other two have got it...
i.e. Death...

 

[awesomeseimei]

Suigetsu: immunity to lightning attacks, or better yet getting powered up by them.

Neji: could have used more development before death, but it's too late now.

Asuma: more abilities shown (also too late). In the databook (?) he was actually said to be the best close-range fighter of Konoha (in his generation I presume).

Shino: make him more outgoing. I know it would kind of defy the point of his character but he has gotten upset several times only due to his own personality. He needs to learn to let go of his grudges.

 

[Keimil]

Suigetsu: Advanced Suiton Jutsu and some kind of defense against Lightining.

Neji: Mastering Another Hyuuga technique, and increase Hakke Kusho damage and range.

Asuma: Showing more Katon and Futon Jutsus, maybe enhanced his blades with Futon Chakra, like in the videogames, but flashier.

Shino: Maybe a Kuchyose contract with a big badass bug, and combine several type of bugs alternating the effects and damage dealt to the target.
