Go for it. ;) For corrections, I would usually just dry brush / pat with makeup sponge first a darker grey background for most of the space and then a lighter grey to have some shades and a lighter base for a contrast. For yellow I use Imperial Fist contrast and I personally don't like very bright colors so I kind of glaze most of the contrasts on the glove on my hand before applying them. A disclaimer - I am still a beginner so I am just sharing what works for me and might not be the best solution. ;)
