Sketches... should I submit them?

I was just thinking that, with all the private commission work I have been doing taking a lot of time ( I am still too slow at it ) it take for ever for me to actually post finished artworks so I was thinking I should post more of my sketchy simple art works that I tend to do a lot of in my spare time rather than just the more finished illustrations and commission work.

Let me know as it could be useful in some way some how.
