Trying to illustrate the sparkle of the flecks of reflected light in the snowdome, contrasting with the texture in the base. Have created the geometric sparkles by leaving them white. Idea is ok I think but the appearance is flat and not like a sparkly glossy dome. Should have varied the size of sparkles from front to back to give more depth, and also considered varying the sharpness of the white from foreground to background.
Puddled watercolour in the base was quite successful in creating texture.
Size is A3 squared off if you can imagine that.
