I took the other idea for the art you showed to me and came up with this...
The idea is that the people are all lining up to give there heart to God. You can see that some of them have heart "cut outs" in their bodies. The final art would have all of them having the "cut outs" and the guy who is at the front of the line , upper left corner, would be handing his heart to God. The colors can change. The sizes of the people can change.
I haven't reworked the other image yet to make it softer.
I need to know which direction you would like to go. So we can focus on it and get the best image for the disc.
