It certainly is awesome that you can work from home and enjoy what you do!
I don't want to rain on the parade, because I think you built a cool deal for home hobbiest work. But, please be careful posting images like this for your business. There a very specific regulations regarding paint booths and safety. I am not an expert per say but have had to spec these in the past for shops I put together. I can tell you that most likely the fan you show and the lights are not rated as explosion proof and are a major OSHA safety issue. I'm not saying I wouldn't do the same thing at home, but if this is your place of business home or not, you may not want to post pics of it in a public forum. I mean no disrespect and and only say this as a manor of community advice. If I am wrong, I apologize. Better safe than sorry.
I do think it's cool and would love to have an area like that as well!
