So I have just managed to finish Part 2 of this tutorial, and below you will find the highlighting steps in sequence for you to follow step-by-step.
After you have completed part one this is what the areas should look like.
So next is the highlighting stage and it needs to be said is one of the most important steps to get right, failure to do so will make the boxes look terrible. So the trick is to take your time not to rush.
Below you will also see some pictures of the highlights themselves this will give you an idea in regards to what colour you're aiming for when you want to highlight.
when it comes to applying paint just target in the middle of the Square less is more
As you can see because you've taken your time and you have built the highlights slowly overall it makes them look three-dimensional.
you can see the finished result quite clearly and it really doesn't take no time at all
so there we have it job done and this technique can be used for any colour at your disposal.
