I'm looking for some advice and opinions regarding a design that looks very similar to a design I sell and make a living from. I have a basic understanding of copyright and I understand that anyone is free to make these style of vouchers and apply their own artistic execution to make their own unique design. However, I feel this design in particular is very similar to the design I created a number of years ago.
The colours, layout and positioning and the wording are all very similar, in my opinion and it looks as if they have just copied it and move two or three things around. There's 100s of ways this idea can be executed and created and there are others out there with their own style and design which look great which are not copies of mine.
So my question is, is this design infringing enough for my to request them to change or or even take it down until its changed?
Below is the design in which I feel may be infringing my design.

Any advice would be great and I appreciate the replies.
