Jolly shandy in color pencil Derwent coloursoft

My first attempt on traditional drawings with color pencil , by using Derwent coloursoft . It is a color pencil but it is wax base . It turned out like a crayon feeling. Color could be blended but layering builds up very fast. It leaves a thick waxy layer on surface which it is hard to put on color . It is also very soft which is not suitable to do detailing ..

Would try to do portrait but as for my skill , I could foresee the result is not desirable .
