I really do love the mood of this painting. It is so serene and gentle. Most of what I don't like about this is technical. Which is a good thing really, because technical problems are easier to overcome in my opinion.

Let me start by saying that I really do love the way you rendered the clouds and the water. Water in particular is something I have trouble with, so I'm always very impressed to see it done well.

The main problem I see is that you are focusing on texture over volume, so while there is a lot of elegant detail, the shapes as a whole don't read well. The character's hair and the leaves on the hanging plant are the most obvious examples of this. His hair looks wonderfully soft, but it looks like a sheet of hair laid flat rather than like something that wraps around his head. Likewise the leaves are wonderfully rich leaves, but they look like they all have little light-sources of their own rather than like a group of leaves lit by the same light as the rest of the picture. The simple fix is to shade the item before adding texture. You can check this sort of thing by squinting or backing away from your picture. Make it so that you can't see the small details and check if the volume still reads.

Another thing to consider is reflected light. That white shirt is going to bounce some light onto the underside of his chin and the back side of the watering can. Also the shadows cast by that bright blue watering can onto his shirt will probably have a slight blue tinge to them.

So much detail and effort put into this from the overall picture down to the details.

Some big strengths of this include the colors, shading (especially on the face), and the background and foreground.

For the foreground, I really like how the watering can and plant came out. For the background, I like how the walkway, grass, and sky came out. I thought you put a lot of effort into the sky as well, which I think is a big plus.

His smiling expression came out great, and I really like how his face came out, especially the eyes. Really well done on this!
