Some things to do with text include making it look like part of the entire image. Some examples are:

Here, I made the text to be the focal, along with Knuckles. Bu tilting the L, I made the entire piece work together and made the text not excessive, but rather one with the piece.

In this, by using the SAO UI font, I created the illusion of having the skill engaged (I know it's Dual Blades, I messed up on the actual text itself). Also, by having parts of the entire image cover it, it seems more to blend in and fit with the overall piece. The colors were picked to accentuate the two main colors in the image.

One of my fav pieces personally, here I used the text to add in a tiger's head, further adding in to the entire image. By making the text very minimalistic, it fit into the sci-fi-space-lightning theme of the tiger, which is represented in the colouring and the text itself (The Lightning Tiger).
Just some tips
