@grappodango If you want to take the contrast one step further. (This is the second part :p) you can make another multiply layer and add a purplish-pink colour over everything (remember the wheel!) Play around with the opacity and erase lightly over your drawn in green light! Hope this helps!
@grappodango -blur some points of the solid colour but be careful not to over do it as it can smear your saturated light to becoming dull! The next thing i did was make an "add" layer and lightly air brush over the green areas to further push the glow!
