I've been thinking about creating my own superhero team book using a combination of Public Domain heroes and some of my own original characters for a while now. Here's a sample I drew over three years ago to give you an idea of what I want to do. As you can see, in the sample, I've used Spark's Atoman, Centaur's Airman, Holyoke's Miss Victory, Fox's Blue Beetle, and I did an updated female version of Lev Gleason's Daredevil.

The team would also include my original character: Moth. You can check him out in this image. I drew this, maybe, five or six years ago and I haven't gone over it with my comic editor, but you'll get some idea of him.

I also have a few other original heroes I'd like to use. The concept for the book would sort of be like Geoff John's JSA. The older generation of heroes steps in to guide and influence the younger. I won't use all the characters in the first sample image, but I'd love to use Blue Beetle and Miss Victory. I know that I'm not the best artist, but, I hope, you can see that I've gotten better over the years. I really just want to create something for the genre instead of just soaking it all in.
Does anyone here have any suggestions or advice? What characters do you think I should use from the PD? Which should I avoid? Things like that.
