the colours arent very nice mate they dont fit try using some blur colours and keep the colour on the render, i think it looks to much blurred overall, the text isnt too good add some main text, light work is ok, the lines could be less visible, border is ok but would be better darker, background can be improved and the sig can be a little sharper overall, kiu mate

first of all, you need to improve the colors and lightin! colors are not very good, and it's too dark overall
lower the opacity of the pattern, or erase some parts of it. make the render stand out more, improve the text and try to add a little more depth to the bg.. and i think the border would look better if it was black or at least darker
