Nice composition of the focal point. Good colors as well. Maybe extend the theme going on in the focal to the background faintly to keep the bg from being monotonous. Nice work.
I like your creativity and what you did with the vectors but the colors isn't working for me. Especially the red vector in the middle looks too strong. The shade of green you chose isn't my favorite either. I do like the overall look though. Good job.
i love the colours, and the way you have composed the picture is really great. only thing i dont like is the background, as it just seems too empty. 9/10
