Kryvaline regular is excellent for line work and the Kryvaline creamy line is very good for bases. Having said that give each a try to see which you prefer best to work with.
Please note: Some Kryvaline colours, for example red, can leak oils when in transit and going from hot and cold environments. They can be recovered by placing in a warm place where they will reabsorb the oil. There is nothing wrong with the paint itself.
