Home made skid plate, whataya reckon?

[noobi]

Well I decided that during the school holidays that I would make a skid plate for my bike, seeing as I cant ride at the moment.
This is the cardboard mock up, im hoping to get some peoples opinion on it, and what they think is the best way to mount it too the frame, before I cut it out of 3mm aluminium.

I think an L shape tab at the back of the plate that slides over the frame rail, and a horizontal bar that goes between the engine and frame that the plate bolts to.

cheers
