Those screenshots look very familiar, and so does the name, the forum too…I wonder why? I think it looks great. Characters graphics are simple and cartoony, which makes it gives it a nice effect, and does eat the frame rate like my background scene for Ronin. If you are going for a cartoony, personally I would see if Cel shading would look good, it worked on Zelda and that Alien game on TGC forums. 
I noticed people were talking about C++ and using it, well there are SDK’s that are supposed to be easy to use, i don’t use C++ but I know of a good SDK for you, has a free water marked version and 2 other packages www.truevision3d.com if the link doesn’t exist, google it:)
