By want of a better name that's supposed to be really meaningful and such I just prefer to give them generic names like Alien Abstract # and Structure # so you don't have any preconception of what it is you're looking at.
Did this one in a paint called open acrylic which let's you play more with the drying time which for me means I get to do transparent layers on top of one another immediately but NOT having to mix my colors again every day which turned me off from acrylics for a long time.
