Hi Teatree,
I reckon you should maybe redo the nose a little more sharpen it up, then maybe the tail could be redone to form a rounded pin ish style, then it may look it bit thick so plane a thinner concave shape to it, if you could also somehow shorten the length a little and then I guess it might need to be less wide so if you can take something of the rails, and with the deck can do something with that, and then if the green colour could go, it might seem alot of work but I reckon it might work, but then it might not too, but heck worth a try? glad to be of help, jobs right mate
