You've captured Donnie's essence, but in terms of ressemblance it's not there yet, due to the proportions problem.
Two ways of solving that: practice and...
Ever seen artist hold their pens and stick their tongues out? Anyway, you take the top of your pen, thumb length from the top, and use it as a unit to build up your picture and proportions. From these "measures", you set out a grid (3x3 inches, for example). And you then fill with detail.
