This is great! The way you drew him looks so cartoony and whimsical--I'd love if Sonic looked like this! Even though he's in a lax and friendly pose, he still looks really energetic and bouncy. Also, I'm usually not a fan of more cyan shades of blue, but for some reason it really fits him here. Maybe cuz that yellow in the background really compliments it... not sure, but this is awesome! Great work!
Cool! Then, i'll work on that for having the same drawing effect as some of your pics! ( Like here: i like the colors but also the line art! ) Can i ask you only one last question, please: how do you usually proceed for making a picture like that one? I mean, do you scan your sketches, then use Sai tools, like the "Linework" Layer, the Brush, or something else? =o *If you don't want to tell me, it's not a problem! Maybe you want to keep the secret! ^^*
