It all looks very nice and is clear that some effort has gone into this, however it is an entirely unoriginal idea with nothing to add originality. That can be overlooked, however, though I'm not sure if this is only on my computer, there is a significant bug where when I am drawing the lines, a large section of over half the screen around where I am drawing is covered by what appears to be the background image.
sorry about taht seems when i uploaded it there was an issue im fixinf it now
