Well thats what happends when you get proper papper, plastic eraser , good pencils...
Sorry but most of the time it has nothing to do with that.
I think this is very well done, there are a few places that could use a little work, especially on perspective, because some of the objects look at odd angles to me, dont get me wrong the rendering and the detail is awesome, but the construction isnt solid.
To be honnest there are places where i think your contrast is totally off, like on some of the leaves compared to the big long stalk, there isnt any grey shades on the stalk, its a harsh contrast of hard pencil and paper which is great if you're whole plant is in harsh lighting but the rest is rendered in a different way. The strokes you used on the plant heads all are very soft and loose and have a nice flow, and has a diverse range of tone however on the stalks there is a lack of the softer shading, while you may have being to recreate a texture, it looks like the pencil strokes were slightly too large and ridgid. Also i feel the leaves are a little plain, i understand sometimes its hard to be bothered to render all the details on the leaf, but i always make sure i render the veins on leaves, and look at how the surface on the leaf is effected by the light, looking at texture in particular.
Anyhows, it is a good drawing im impressed ^_^ keep it up
