i think you could generate more interest if you make some kind of blog where you describe in detail what problems you come up with and how you solve them instead of just showing new feature shots.

all in all its just some technical playing around for yourself or a game for yourself. almost all smaller teams fail developing a new game engine that probably why a lot skip this.

i like your screens really but for me its not interesting because you just show us the screens and dont tell how you actually did that, where you got the knowledge from and so on... and the shots are not sooooo nice that they amaze me although they look good. i just think, oh another nerd making the own engine, lets see how long he lasts

thats my honest opinion, hope its not too hard. i also think a general gamedev / engine forum could help you get more feedback. good luck with it. hope you learn a lot while doing this.
