Dark colour subjects on pitch black backgrounds is not the best way to present your work. For simple renders focused solely on a single model, get a neutral tone, like a grey so it highlights the form, but isn't super strongly contrasting to the subject.  You've got the silhouettes down for what look to be a Lanchester and De Lisle, but from the little I can see, it's not very accurate to smaller scale details. Also use more lights, a simple three point light setup is pretty standard and will definitely help show off your work better.
