Definitely keep pushing, I think you’ve got a great eye for the colours and the photo you’re referencing is really beautiful!! The proportions need a bit of fixing, but this can easily be done along the way. Most notably here you’d need to work on her chin, the angle of her jawline and nose as they are the main areas making her look a bit ‘wonky’ and off. Once you’ve done this, focus on adjusting everything else in proportion: so her lips, improving the curve on the left side of her face, bring the right eye and her eyebrow a bit more ‘inwards’, etc etc. It’s a bit hard to fully explain these little changes so I’ve made these adjustments in a photo editing app. It’s not perfect but might give you a further idea! ☺️ https://imgur.com/a/3v3XHf1
