Hi John,
As a comment on the shape, it's the transition from the coloured area to the upper portion that looks a little off to me. I think it's the proportions, the top should taper in (be waisted) more, it's too much the same size as the base.
I quite like the shape without the upper portion, that works for me but would be more a cup or open vase.
You say you've applied the colour with a perfume sprayer - I presume an atomiser (the sort with a squeeze bulb?) - don't put the colour scheme down, it'as bold enough to be interesting. If it's your first go with colour, it's an interesting effect you've achieved.
You don't say what wood or give dimensions though.
