Another great piece. I think it would be nice to see a little more color perspective in it, though. That is, the trees and stones in the far distance should appear lighter and bluer than those in the foreground. It's probably not very easy to do with markers, but it would add more depth to the image for sure. You might be able to get the same effect by increasing the contrast in colors in the foreground; make the shadows darker and the highlights brighter. The lady's pose is a little awkward too, as if the stone bench is not flat and she might slide off of it at any moment. I suppose that happens when things start as a quick sketch, though. Other than that, I really like this piece. I find it full and interesting. It seems to have a larger story behind it. Keep up the good work.
I like the details on the background, the scenario is really well drawn ^-^ has a nice composition! It looks awesome on the details, but I'd say you could add a little more colors instead of a single shading, the color works well but can be more stunning
