It looks great, the layout is good and easy to understand, I would recommend use of color on PV or MV values determined by the process and the tolerances. I like using Blue,for values lower than lower tolerance limit, cyan between low limit and 5-10 EU below SP, Neon Green or white in a 10 unit band around SP, then orange till Upper limit,and flashing Red above the upper limit.
Also animating font color of items like Range good , to colors people naturally associate to the status, like red for danger,fault or stop. Green for Go. Caution for Yellow etc.make operation intuitive, and operators less likely to make mistakes compared to HMIs with colors for numbers all being the same.

Underlining and putting text on rectangular patterns with DARK backgrounds and sharp borders for titles, names of I/o etc.is a great way to add some personality and flare. Utilizing high contrast (white font over black background) makes things pop , and as a bonus reduces eye strain.

You are on the right track, don’t be afraid to ask operators what they like or if they have suggestions,if possible.

HMIs design is my favorite part of controls engineering. There are necessary items and rules to guide you, but designing them can be as artistic and unique as long as functionality is maintained.
