Its a good design although I must say it looks the Fiat 500 paid a visit during your drawing phase! lol. In any case I think the body and glasshouse is original, you should try to change the front end so that it resembles the overall theme of the car. Not a bad idea but you can improve.
interesting idea but you could express it better with drawing/rendering that shows tighter forms. As of now, it's a bit difficult to read the forms on the greenhouse/pillars and side skirts.
