Vision: I can see where you are coming from, the concept is very easy to see that you wanted something slightly teasing and sensual. But at the same time it's not done very well, the shading is off by a long shot, as is the coloring and general build of the picture.
So 2.5 on Vision because you tried with heart but failed.
Originality: This was simple, you clearly did something original and never done on your account by making this art. But It's still not very original, half naked heart holding clawed demon/dragon women are the farthest thing from original because people draw them all the time.
3.5, You tried and it's the most original for you but that's not saying much really.
Technique: Honestly very terrible, As I've said the colors are off, shading, light affect. Everything is very very off when it comes to that, but the drawing is also very terrible. You can see where the tail meets the body that it's very abnormal and awkward. The claws are all different lengths and pointing in a different direction. The lines are all pretty rough and it doesn't look like you put much effort into smoothing them out at all. The straps of her shirt are really unnatural and it just makes the picture look poorly constructed.
.5, Very very poor technique that needs a lot of work.
Impact: The picture has little to no real impact, it's a carbon copy of so many other images on DA that are of a lesser quality that it takes away from what beauty could have been displayed if you had tried harder and put forth a bit more effort on this piece of work. The impact is negative if at all.
1.5 for this astoundingly bad image.
I however do not think you are a terrible artist at all, you clearly have potential in art. If you work hard, practice daily and maybe have some friends help you with your drawing, watch some tutorials and take advice, with your artistic eye you could be wonderful don't give up.
