Hey mike, nice work! kinda jealous that i wasn't that serious with painting when i was ur age! But, I kinda feel like everything is too fuzzy, like you're trying to render everything all at once. you should try to do more studies of just colour, not just rendering, but like, trying to pin point what blocks of colours are used (squint!) and think about why it's there and confidently apply it in as few strokes as possible. it may end up as a more impressionistic style, but that's kinda cool too and a lot more definitive -and less all over the place.
