To Make the arrow twice as large, you just need to convert every character of your string into a string, including the empty ones (spaces)
print(" "," "," "," ","*")
print(" "," "," ","*"," ","*")
print(" "," ","*"," "," "," ","*")
print(" ","*"," "," "," "," "," ","*")
print("*","*","*"," "," "," ","*","*","*")
print(" "," ","*"," "," "," ","*")
print(" "," ","*"," "," "," ","*")
print(" "," ","*","*","*","*","*")
This will add a space between each character and make it twice as large, and you won't have distortion problem
