But I don't understand how to do Step 4, the color dodging.
Searched some information on it and tried some things, like blending of the ellipse shape, selected the color dodge option and making it totally yellow for some reason.
Could anyone explain how I should do Step 4?
Thanks in advance.
EDIT: finished the pic, this was purely meant for exercise, so it's kinda empty and stuff.
This is like my first work made with Photoshop
