oil pastels

one thing i cant stand working with is oil pastels, they just dont do what you want them to do. but i soon realised that if i kept them in my hand instead of putting them back on the easel that they warmers up and started to blend a little better, but i was stick struggling to create secondary colours that didnt just look messy. this was when i tried putting white back into it, the white helped loads but it still just looked patchy and just weren't working how i wanted it to. i decided to create like a skin like barrier over the colours id already put down by using the white, i did this by following the contour lines of the body. but it created like a film over it so the colours weren't as bright which worked a lot better than before. i think next time i use oil pastels i need to develop this style further as its starting to washed out, i think i just need to work back into it more and more until i am happy with it
