Looking good but wait for it...
Pole barn style construction but with steel? I've not seen that before - what drove you that direction?

how deep did you go with your electrical feed? looks shallow
Looks good, I have a 24x30 metal shop too. I like how you insulated the walls and such. How did you wire up your compressor outlet and your welder outlet? I'm at that point in my shop now, getting power to the building.
Do you have any problems with moisture?
