Aaah yeah your edit looks better. I'll try and look up how to better use proportions and shape of a body but one thing I'm having a lot of trouble with is picking and using colors. I know it'll look better if i read up on how to use proportions to my advantage but until I read up on that and redraw it I'd like to know how to pick and use the best colors so I've been working on the head I drew.
I've got several problems with what I've done for one it doesn't look right and while picking the colors I pretty much purposely went for something similar to what you've done because I'm not too sure how the whole thought process behind picking colors works.
Things like contrast and making sure I don't use too many or too little saturated colors I sorta understand but with things that are hue related I sorta understand a bit less. Like for instance I'm not sure if you made your palette because you knew you'd need purple and red so you worked it out to include them or if there's some other thought process that helps you choose colors that you need for your image and would look nice together.
As for using the colors with a limited palette I find it sorta harder to know where to use them. You used your purple as an outline + for the things that actually are purple and it looked good but normally I wouldn't think to use the purple as an outline but I thiiink you did because it was the darkest shade?
basically I'm having trouble understanding colors and I have read up on it I'm just having trouble wrapping my head around it so if anyone could help me understand it or give me advice on coloring the head in general so I can sorta get used to it I'd really appreciate it.
