I personally think it's a bit of a waste of memory on your laptop/ pc having a huge background and a little design in the center of it. The sotw was to do with purple the only thing that stands out to be purple to me is the design behing the three squares because the squares look more pink/ light blue to me. The use of getting the curved lightened parts on the squares what quite good and i like the design behing the squares but its not really got much detail in it. 2/5 from what you've given mostly the large background is what is making it so plain looking
