My philosophy is to expose everything so that you maximize the usefulness of your stuff. Its a work in progress as well, but here is a peek hope you guys like it!!!
I dont know, looks cluttered to me. I like everything put away, in its place. And the spray paint's, keep 'em in a metal fireproof cabinet along with anything else thats flammable.
We'd love to see more pictures of your space. If you came to show off progress and to seek suggestions, you are home
You will get a lot more advice to come, but for now it looks like you've got a good space and have some projects ahead of you. I think I understand your 'open' concept and you've got a good start with that slat board - it is very modular. Let us know how we can help
