Houston we have a problem

After having modelled few plants I wanted test them so I`ve thrown everything into one rapid messy composition.
Actually no textures were applied which does not justify how BAD this thing looks right now.
I planned adding more variety, doubling, tripling the number of plants, flowers, ivy, trees... Adding colorful, bioluminescent texture maps... But on how this thing is turning out I might just scrap it all.
Any ideas, suggestions?
