You do not have to be ashamed of what you do, because you do a great job, your comic looks very, very good and I think that everyone who sees you admires what you do.
For me you are a great artist who is where he is for his great effort and dedication. You are a role model.!

The pencils look great! you have good options there, it's good that you conoscas and facilitate your work.
An easter egg? hmmm I do not know, it looks like a cover of a comic maybe
I see some letters and a figure of a very muscular man, but I can not read it well because of the angle. :(
Well, the two are comics hehehhe.
Luck
