Thanks a lot for your feedback, Ronnie! I´m really trying to work on my narrative, thinking how to make it as clear as possible for the reader, so thanks for talk about it; so glad you liked it.
These Superman´s samples are done without any script, just trying to créate a quick sequence when I can show backgrounds, real people, narrative and a bit of superhero action, trying to convince some editor that I can manage a variety of graphic scenaries.
About the big bad guy, not sure who he is; just a random cosmic villain, in a Mongul/Darkseid vibe
Thanks again for your kind words and for taking the time of sharing with me your thoughs; best, man!!
