Very efficient use of space.
Everything is clearly labeled and ready to go. A nice design for a printed sheet.
I've laid out sheets for our "playtest" sessions (and for one or two of the recent games) , and (after damn near 30 years), only in my last revision did I combine Traits with their skills. These are more intended for use in the Epic Table VTT so there's a different layout than for paper.
One thing on my current sheet you might want to adopt is adding in some markers for inherent skills. I split those into a panel and assigned numbers to the inherent skill then appended those numbers (where applicable) to the main skills. That way I never have to look those up if I level up mid-mission.
Only other comment on your design is maybe boxing out a space for a picture. I've always been one for doodling a drawing on a paper record and finding suitable art for a VTT record. That's just me. 😊
One a phone now but, next time I'm on my gaming machine I'll try to remember to upload my current sheet for you to look at.
