Thanks for the input, chums. It’s really helping me to focus my ideas.
I really didn’t notice the similarity with the Battle of the Pelennor Fields until I sat back and looked at the sketch. Dumb, eh? I’m no fan of the recent movies, though enjoy the LotR books very much, but either way I don’t want to create a pic that has such a close connection with any existing imagery so I feel as if I can leave this concept behind quite happily.
Generally, I think I’m in agreement with Plagiarism that war and conflict aren’t all that ‘spectacular’ so I’m going to see if I can’t come up with something a little different.
