Color Palette Challenge

Petrol!! Timba!! Doyle!! Sokko!?!  

[~Explode~] AAH!! This is so unbelievable! Sorry for my late answer~
I feel so surprised and speechless!! SUPERR AWESOMEE!  
I have loved your amazing color palette challenges so much, but now! AH!  
You have drawn each one really personally and using different techniques that fits so well in each one's personalities.
In Petrol you have used beautiful stripe shading which looks refined and smooth but cool as the same time!
In Timba you have used bold colors and frames making really neat impact!
In Doyle you have used complementary colors and dynamic shaded lines which makes the picture look pretty awesome!
And my personal favorite, the one where I can't get my eyes off, Sokko! _{of course xD} is wonderful!
That dot pattern fits together with her personality so well<3 It somehow makes cheery mood in the picture and DAMN I LOVE IT!!  

Thank you really much, you awesome and sweet little Ethai-sama!!  You are the best~
