Hey there. Thanks for the sweet comment and high rating!!
You were asking for suggestions on your design and I didn't want to throw that thread off by posting again.
What kind of gangster look are you going for?
If it's "street" I'd get rid of the umbrella, hat, and leg pose. They are more "thug".
If it's something along the lines of Al Capone they were more uniform with their clothing. Meaning the tie, any accessories, and shoes always matched. Your current hat & jacket would be great but, maybe change the color of shoes?
Just some ideas. You will probably tell me to go jump and that's ok!!!
Have a kick a** day wink
