Do you mean you made the texture background ? It is nice and neutral, useful for many shades and looks good behind these flowers but there appears to be a line down the right hand side.
The flowers and vase look strange - there appears to be a slight reflection but no floor - maybe just drawing a slight dark straight line across the bottom would change this. The pattern is very visible at the edges but blurred behind the vase and flowers and the first space just above the rim of the vase looks very cut out - maybe putting a layer behind it with a flower or leaf and blurring the edges slightly would look more realistic.
Overall I like the layout and the matching pink border and can imagine it as a card design but needs just a little more attention to little details to be perfect for me
I have had a quick play to try and show what I mean, if you don't like it I will remove
What size do you find it is best to make your textures? I have been making a lot of new brushes recently but have not tried many textures so far
