EDIT: thank you for 500 favourites and a thousand followers!!!! omg was seriously not expecting it to do this well;;; I forgot to add this in earlier, but if you do use this tutorial I'd love to see the final result!!
UHHHH I DIDN'T GO IN TO ALL THE TECHNICAL+BASIC STUFF so if you don't understand anything don't hesitate to ask!!!!!
Final piece here:
F.A.Q What programme do you use?
SAI for everything. I only use photoshop for text and geometric shapes. How do you choose colours?
My general rule is that if your highlights are warmer than the base colour, your shadows should be cooler than the base colour (for example for the bat boy DARK BLUE SHADOWS/BLUE PURPLE BASE/ YELLOW AND RED HIGHLIGHTS); If your highlights are cooler than the base colour, your shadows should be warmer than the base colour. (In the hair step by step, MAGENTA SHADOWS/ ORANGE BASE/BLUE HIGHLIGHTS)
but there are also exceptions to this rule, the only way to find out is too experiment!!!! How do you make your colours so bright and vibrant?
DON"T MIX IN BLACK THAT JUST MAKES EVERYTHING RUINED OK What tools do you use in SAI?
I literally only use the pen and marker tool, but I keep adjusting the opacity/minimum size and the shape of the brush to fit whatever I'm doing.
