Here’s a studio example posted by The Blushing Bird.  Although I would encourage this artist to completely clear her floor, invest in a better table, invest in some direct lighting, invest in a better ergonomic chair (preferably one that matches her shelving scheme), and get rid of her temporary plastic and cardboard bins, what DOES work here is the use of color on her walls and shelves.

With yellow to the left, and exciting orange directly in front of your vision, complimented by red/orange long shelves – what she’s got here is a real start to a highly creative in home art studio space.  

I also think it’s important to have your tools within arms reach and it’s often a balance between tools and decorative items.  With a little bit of shifting around of the photo boxes, bins, and baskets, this space could be more workable with a little less visual confusion. Great wood shutters on those windows!

I would also consider shifting the table slightly to the right to take advantage of that window view.  I see the bookshelf doesn’t fit under her long shelves, but it doesn’t appear there’s that much material in the bookshelf now, so we have to reassess its value.  By also shifting and rearranging those items onto the long shelves, this artist could consider removing and selling her bookshelf and taking advantage of natural lighting by moving her seat closer to the window.  If the bookshelf must stay – paint it the same color as the long shelves for continuity. Sometimes less IS more.
