I like it i'm just not really feeling the C4D's texture, I see what you've tried to go for but the shinyness makes it look all unnatural, bar that its great and has good compo :]
Can't say I really care for it. The C4D itself looks like it's decent quality. However, it doesn't match with the stock at all. I really don't like those C4D parts you put on the sides/top. If you still want to try this concept I'd suggest a C4D render that resembles a vine, or something more natural looking. (Maybe tree roots?)
i think the center C4D looks pretty good it blends a little with the background only the effects arround it look a little out of place
