WOW! Amazing detail in the background, the only thing that could upgrade this image would be textures (though it'd be a lot more work), some cloth-like texture, a woven-like texture for the baskets, some bark/leaves texture, fur texture, and grass (the gravel path is kinda already textured due to the pebbles but you could technically add a rough texture to the rocks). You did an amazing job though! I would start with getting familiar with a little texture added to one place or another, and slowly work until you're using more and more textures!
