this ia beautiful, i hope its on watercolour paper, the eye is just stunning, and your shading, love it, keep at it, good luck with the colouring, i know the feeling, colouring can be a daunting thing, especially with watercolour, cause your like is this the right colour or isn't it, but its best to try, what i would do is if u mix try on another piece of paper, then you can be confident it is the right colour, though i love watercolour :), bad thing is its expensive haha, good luck :)
