Help Assessing Windowing in an EC (videos included)

[Lemonlime]

Hello! I'm embarking on a fun labgrown alternative to switch out with my e-ring and I'm in the market for a EC with w 1:2-1:35 ratio in the 6ct range. I've reserved this diamond but I'm wondering if I should let it go. It appears to have some severe windowing in the left center but I'm not sure if that's just a tilt window or a bad enough flaw that will bother me when wearing it. I would love to hear from any experts, @Karl_K please weigh in!
