I can see you're improving but the C4D's are too contrasted so basically it looks like little spots of colour with no structure behind it. There's no direction or depth in regards to the focal point, I'm left trying to figure out her position in relation to everything else, is she in the foreground/middle/background. Too chaotic, you're trying to put everything you've learnt into a single piece. There's improvement but you more or less need to work on composition.
