I like your color mix. I think I would put more sharpness into the foreground and in the water make some higlights . The water furthest away should be the darkest. I think you did a pretty good job so far. Take a look at this..it may help http://cellosoft.com/2draw/wiki/index.php/Lascaux_Sketch

Wow this is BEATIFUL. I'd love to go fishing there! it's magnificent!

I like this picture very much. I agree that it needs more sharpness in places. The places depend upon your intention.. I see the plants as mostly underwater with the water surface being the defining line.. in that case, the plants and grass above the water line need sharpening. If you intended the plants to be in the foreground with the the water as the background, then the whole thing needs sharpening. Hope this makes sense. :-\

thank you all very much *^^* I will work on this some more with what has been stated ^^

I disagree with davin about the water that is furthur away being the darkest. Its not nessesarily true. Maybe if it were at nighttime. And I also disagree with emma, If you want your focus to be on the plants in the front, that is where you should be more detailed. Not even nessesarily sharpened. The background you can get away with it being more out of focus. And with shading, things closest to the sun should be brighter. Since there isn't anything blocking light.
XD It is really nice, what you have. I think you have a really good feel for backgrounds!

Actually, I don't mind the coloring at all; it's very pretty, and could be more so if it was more defined. Also, I think that it would be much more powerful compositionally if you lowered the horizon line and/or raised the hill in front to make the difference between the two really stand out. I can't do landscapes for beans, but you really have something going here--good luck!
