New aqua colours White night

I bought new Russian colours and was playing with them (I have never used the watercolour before).

I do not why I was stuck to dominant colour, maybe the inspired painting by MIRO. It did not work to me. 

I changed the dominant colour to bright blue: I have noticed that monochromatic structure looks good .............

............... till I added the lemon yellow and the circle shape.

And it looked awful when I add Scarlet red.

So I played again, just with scratched and the result did look childish and for me in this time balanced. Tomorrow I will buy more colours and I will keep playing with them.
