Thank you for your response, Dingobass, gives a lot of direction
One quick question though, when you say 'feather blend it into the lighter colour", do you mean to say that I should mix the two together to help make the burst seem more natural at the points where the two colours mesh? Or to just take extra care when meshing the two colours and applying the outer colour delicately? Sorry if that sounds convoluted.
Kind regards,
Nathan
