Paradise island by David Sim

Well, it could have been a real location. There's a video by the sadly late Terry Harrison, maybe still available on the SAA website, I don't know, which could help you with this. You could do with some sharper definition of the figure, to help her stand out against the foliage: a bit of thicker paint and stronger colour would help. But March 2020 is no time at all - keep going! More and more paintings is what you need to progress - I like your composition, it's just improving the execution that's needed: and practice gives you that.
