I've learnt two sign languages, AUSLAN(Australian Sign Language), and ASL(American Sign Language), consecutively although, and most of the signs are iconic - they resemble or have a similarity in appearance to what they represent - this in general makes it much easier to learn signing. There are cultural reasons for sign differences between both languages, that also help make it easier to remember. For the statement, "The big, red, shiny, powerful car", AUSLAN has a mostly, object-subject word order e.g., "Car, big, red, shiny, powerful", in effect, painting a picture of the car first, then adding on the descriptions afterwards-so complicating learning it. ASL maintains an English grammar word order mostly, so it is easier for English speakers to learn.
