Lucy in the sky Cover

the only issue i really see is the diamond looking shape it throws the design off it doesn't feel like it belongs in the piece at all it also draws you away from the more important subjects (the characters)

maybe if you made it more transparent and you could see the other objects and colors behind it might look better

or another solution might just be to make it smaller you have a lot of colors and shape going on and if your not careful you can over crowd the art piece and throw off the balance

other than that your color scheme is unique or at least I've never seen anyone use that color scheme before

the drawing style is very well done and creative and a little random to the audience or it seems that way to me but it works for you

overall its a good piece of art just that the diamond throws it off but im sure if you want to keep that in this piece there are ways you can figure out how to make it work
