You've got the basic idea. I like the more complete chemical symbol with atomic weight, etc- think it helps to make it obvious that it's the symbol for Iron. Also, something a little less reliant on color- though I like the idea. A good amount of our print will be presented in single colors or black and white- I like color, but it needs to make sense even in black and white form. Thanks for the submission!
Thank you for the feedback. I will get right on it as soon as I get home tomorrow. Please don't le t other people know what has been said to me as they do copy other people submissions on this site.
