The shape of the model is (for a primitive low poly model) acceptable, the black edges look ugly and you should use textures instead of colors if you want to improve the look of your models.
I can easily create such a model in 5-10 minutes.

Hell. I feel like re-texturing every single Stranded II thing, but S3 is going to be released in about two years so fuck it.
