Pretty nice! As others stated some issues with light maps but mainly only seen in that first image prominently. But do not sell it for $5. Sell it for what it is worth other wise you are hurting not just your potential sales but others too by devaluing the work 
2 weeks worth of work even on the side for fun or w/e should be more than $5. The video is kinda weak I feel with the camera angles and speeds. The last two shots of the dolly forward and then dolly back I think is taboo like that in the cinema world but I could be wrong, it just felt weird to me for sure.
