I was not sure if you wanted to portray more delicate work or more industrial and raw (forging). Based on the brief and your keywords "sleeves rolled up, hitting, anvil, hot furnace, molted steel" I chose to go more industrial. Also, the fact that the name (though it comes from the AZ city and means "big house") has the word "grande" which is recognized by non Spanish speakers. For these reasons I chose to go BIG and raw for the imagery. However, I can re-illustrate the blacksmith. if you prefer, show more detailed or fine working of the metal. Please let me know your thoughts or if there are any revisions you would like to see. Your feedback is invaluable to helping get the perfect logo.
