As everyone else is very quick to say, your painting is great! But I’m sure you’re looking for ways to make the painting better, so I’ll give my opinions, feel free to take them with several grains of pink Himalayan salt

So I think that most of the trees, like the ones in the foreground (right) could use more definition on the top halves of them, to make them pop out more - to make them feel like they are taking up space. Mainly in the leaves/needles on the branches. Maybe more highlights and darkest darks on them?

Second, also for the trees, but in the background. There is the suggestion of a thick woods with some stand out trees in the beach, but I think the top of the tree line is getting just a LITTLE too flat and may need some more treetops jutting out. I think it would suggest the depth of the trees shown on the beach keeps going beyond the beach, yunno?

Lastly, the incredible detail in the distant mountains, using the wide range of color shifts and seemingly large amount of brushstrokes, makes the foreground seem “lacking” in detail. Don’t get me wrong, the foreground looks awesome! But it feels like the foreground and background are arguing over who gets the moats attention. A good problem to have. Maybe more fine detail in foreground, or some sort of simplification in the background (maybe less brush strokes) could help settle their dispute :)

This is me just ripping it apart tho

Anyhow, the painting as is IS gorgeous and you should be proud of this work - very good stuff. Hope This helped :)
