If you mean my sketches for the watch I have posted some of them on my instagram, and will try to post more! :)
Exciting that you are also doing your own sketching, you shouldn’t worry about them not looking nice, they are only meant to be a quick way of making a note of your thought or idea.
I find it a great working method to use different styles, some very quick freehand, some more technical, large scale, with rulers and such, to work on detailing and then into 3D modeling, 3D printing etc.
