We like the circular shape, the red curtain and the truss. Can we see it without the stars and hang two lights? Cut the wrench at bottom center, move the mics closer together. Can we see a blue curtain version of that also?
# 62 looks like a smiley face with a handlebar mustache. Can we see the lights in profile or at least a 45 degree angle? Connect them to the truss and show me more of that. Tilt the mics up a little more and remove the wind screens. Let's see the name in the non script font, all caps, larger.
You are getting there but still a little cartoonish. Use the real icons for the following items: Two ETC Source Four ellipsoidals on the outside and one Altman 8" Fresnel with barn doors in the center. On the mics try a Shure Beta 87 shape.
It was getting a bit messy for me with barn doors, so I have left those off. The highly technical aspect isn't really my style, I prefer to keep things very minimalistic - you may have more success in this case with another designer.
