Great stuff & they don't look like any specific characters to me. Make sure not to make any inference to any either except in a generic way. Besides, the clothes more then anything define a vast majority of the characters. Most lawyers talk out of both sides of their mouth anyway so you don't know what to believe from them, I wouldn't give them a dime for their "advice" because you will find another one that will say the opposite. If you do find one that will give you "good" legal advice ask them if they will pay your fine if you are sued for infringment & lose.
