This is looking better and better man, can't wait to see the final projection. Your details are coming along great as well. Don't neglect his hand though, (your left) right now it looks like he doesn't have one to me, getting lost in shadow but you can still see his cuff so it looks like its cut off. Nitpicking!
edit: one more thing i noticed. bring your speakers forward (darker) a bit more. they look like they might be on the same plane as your background right now and I'm losing them. They look cool though!
The projection is dividing the artwork into two different area . . .Maybe something to link the projection to the entertainer at the bottom right part of the composition.
Mmmm [thinks] . . . maybe gently erasing some of the projection at the top right to darken the top corner might help to link both areas more. I don't think it's a major problem but I'd be tempted to let some of those pipes and stuff show through a bit more top right. I'd like a few more areas of pin sharp focus (even just suggested detail with really thin lines).
Anyway, looking great. One of my favourites from all the entires posted here, very painterly and the colours are brilliant. Good luck.
This is looking so good, yours is my favorite so far! Detail is looking good, the lighting is fantastic. I think another level of detail on top of the projection will really help it though. Like those particles you see in rays of sunlight, just little speckles where it hits just right, in a light blue. Your greens are taking over now, you should try to vary it just a bit, warmer and cooler blue in touches. Your light is warm and your shadows are pretty warm too, it almost gives a murky feeling to the image, which you might like.
And the speakers stand out wonderfully now, perfectly done!
