Hello ! I made this anime character head (i’m just beginning Blender ^^), do you have some advice to make it better ? 
Although, i would like to know if there is some good technique to make an eyes closing animation (do i have to model the eyelid separately or perform an extrude for example ?)
Welcome to the Blender Forums. Looks good, especially for your one of your first projects. However, I think his eyes might be a little too high. Also, if you want to make a blinking animation, you could probably try using shape keys and model a key with his eyes closed.
Thank you for you feedback, i’ll try modifying it ! Do you use a shrinkwrap modifier for the eyelid ? In all the tutorials i saw they used spheres to make it but it isn’t suitable for deformed eyes like here 
Hey bro good work so far. For some add vice id say you should youtube “David Ward” the youtube account is called “the d-dub show / ward7299” hes got ton of tuts:yes: i don’t really follow him any more but look up his johnny blend part 17 he will explain it to you the shapekeys Good Luck.

You should give the hair a little bit of translucency.
If you need anime textures, just get a real texture and use gimp’s cartoonize plugin 2 times and it should look cartoony.
