Criticism is either a path to more productivity or zero productivity. Interestingly, getting feedback for a design is a normal part of the design project. So, when people approach you for feedback on a design, they are looking for ways to see with many eyes and thoughts for the sole purpose of achieving the design goal. To give creative feedback, follow these tips; 

Tell The Designer What You See At First Glance. 

What does it look like to you? In other words, share what you think the design means by going by what you see. This will help the designer to know if he has communicated his idea and help you customize your amazing sticker printing design.

Tell The Designer What You Think The Design Is Trying To Achieve. 

Can you see any connection on the design that it is trying to achieve anything or that it wants to make the viewers see or do anything? If not, make it plain to the designer. The designer can always know if the design has achieved the goal by this.
