The final execution for your design campaign or any design project that you’re doing should focus on quite a few things. You should focus on the layout structure itself, you need to make sure everything is in harmony and everything is balanced. You also need to focus on the major backgrounds that you have in your piece along with the large regions of the page. Afterwords you can start putting in all the necessary detail and information from the top of the layout to the bottom.
As you finish your project, you should always consult with your mentors and peers about the layout and the design in general. Most of the time they will like it and if any changes should be made they should always back it up with a reason behind it. Some changes you’ll make would be pure sacrifices, other changes will be improvements, but overall there would be a more positive outcome then the negative.
Just make sure that you stick to the requirements that were given to you at the start. If you think that you’re idea will look better then what was assignment then do the one that was assignment, and do an extra one for yourself. When you present the two pieces the client will see that you care about your work and might reconsider the changes and maybe even give you an extra tip.
The whole point of the execution is to put everything in the final piece that will be ready to present. There will be very little changes from the sketches that you’ve drawn to the final piece. Most of the time you might change some colors, or move a few things but generally speaking you’ll see a lot of similarities between the sketches that you’ve drawn and the final piece that you made.
