Sorry to tell you, but you put a toy store paint job on your bike, and with the mixed set of components it worth what a used toy store bike is worth. Virtually nothing, except for what any of the component that are salvageable would sell for. Look on eBay for component of the same model in the same condition sold for. Not asking price, completed auction price.

Personally, I would put a value of ZERO Dollars on the frame in it's current condition.

Seeing how the bike frame is way too small for you, if you are trying to get to a more reasonably sized bike that you can ride, your best bet would probably be to buy a frame the right size, and move your parts over onto it.
