Whaat?I mean, this is awesome!The concept is weird and cool, a bit like a parody on the cornucopia (judging from the description you did have that in mind). Heh. Cor-nucopia. (Cor is latin for heart.) However, I'll give the concept a 4.5/5 because there's no way a heart this big wouldn't break the fragilely fixed box underneath.Anyway, this image would beat competition rather easily with the colours and the colour distribution alone. Kudos. It's so luscious. And while your shading works rather nicely, the way you play with light is even better. The best part, of course, is the water. I have no idea how you caught the transparency properties of large-bodied water so well, but that's the favourite part for me.Almost forgot: You also did very well on the composition of the image. It's quite dynamic, with a bow shape going from the rocks, through the water and ending with the horn. It makes it very dynamic, gives everything a sense of direction and shifts the viewer's attention from one part of the image to the other.When you're this good, it's no wonder that the image looks great. The only thing that could bother people is a lack of continuity. Which is the case here, at least a little bit. The shading is great and the colours are rendered, but the rightmost part of the horn is poor in detail - even though it's shaded heavily, the sudden drop of lines looks like a big unsharp blotch. This is worsened by the fact that the horn is the main focus of the image. It might work if this kind of thing would be consistent with the rest of the image, which plays with the depth of the image and redirects the aundience's focus, but I don't get that impression.I can see a minor, but similar blotch on the rightmost rock.Everything else is fantastic. It's clearly showing your skill. There is the question of the purpose of the artwork; if it's something you did more for yourself than for a commission, this is more than fine, otherwise the only limiting factor I can see here is, to render out everything evenly or continuously.
